Thanks Lancman,
I’m a 3 hour round trip away from the museum at the moment and dont have the Lincoln manual with me either.
I had hoped RF342 may still have her’s intact, but a quick look through my photos of the Centre-section when it arrived didnt reveal it?
Here is a general view, can anyone identify where on the main spar it might be located?

Mark Pilkington
Thanks to everyone who has replied and offered their assistance – we really do appreciate your support and speedy responses. Please see a photograph of the item we require shown below;
[ATTACH]184398[/ATTACH]
BBMFPRO,
I was assuming this item is located in the cockpit? but the photo looks like its on the wing spar somewhere, is that correct? and if so where? as its possible the same unit is used on Lincolns?

Hello Elliott,
thanks for including the contents of my post on CAC part numbers, I noted however that some of the CAC types are still listed in the main body with erroneous or incomplete prefix numbers, (Boomerang, Wackett & Wirraway) provided earlier by someone else, which was the basis of my post to correct them.
Leaving them as they are still risks misunderstandings or mis-identification?
I have highlighted those below in red, (along with proposed corrections), you may wish to correct them, or simply delete them and leave the CAC types referenced to the contents in my post? (its unlikely many CAC parts will surface outside Australia in anycase).
I have also added the CA-10 part number into the Wirraway details in my post, (also currently in red to highlight the addition.)
I will leave it to you to finalise, inclusive of any other additions or comments others may make.
Regards
Mark Pilkington
hello Oscar,
thats great, I hope you lodged a HMP comments form in as well? and theres still value in circulating it to association members etc and encouraging them to lodge late comments into Monday/Tuesday, as its not a tender process and late comments shouldnt be rejected within a few days of the closing date.
regards
Mark Pilkington
bump,
although the comment closing date was 30th of April (extended from 30th of March) I am sure emails recieved across the weekend would be accepted.
hopefully the attachment is accessible, it is a pre-loaded comments form, which can be completed with name/address etc and emailed to the address listed on the form.

I’m not sure the CSU’s for the Gipsy Six and small engines would be the same as the hydromatic props in any case.
I collect original DH engine / airframe manuals and have 3 original prop manuals:
The de Havilland Hydromatic Propellor – Service Manual
& the de Havilland Hydromatic Propellors – notes for pilots and ground staff,
neither of these details the types of CSU’s by model.
The de Havilland Controllable-pitch airscrew constant speed (spring and pressure operated types – Service Manual.
this one doesnt cover the CSU’s at all because it refers to:
The de Havilland Controllable-pitch airscrew – constant speed control unit – Service Manual. “available from the Stag Lane works”.
My DH Engine Manuals dont seem to cover the CSU other than in general terms:
Gipsy Six (series I) – no mention
Gipsy Six series II – mentions “optional extra equipment” for oil system modification and governor fitted for use with DH constant speed airscrew
Gipsy Queen II calls up the BX series
Gipsy Queen III calls up “fixed pitch of approved design”
Gipsy Queen 30 – doesnt address the prop CSU at all?
I have multiple copies of the Gipsy Six (series I), Queen II etc, with some carrying additional sections or leaflets/booklets covering starter motors, magnetos, fuel pumps etc, none cover the CSU’s?
The elusive CSU manual from Stag Lane referred to above seems to be where all would be revealed?
google yields the following:

Bloody politicians. They’d flatten the place and sell it off to property developers the first opportunity they get.
That was the intended outcome from 1998 through to 2001, we locked in the operating airfield in 2001, locked in retention in government ownership in 2004, and protection as a National Heritage site in 2007, now we need to lock in what and how it is protected as a National Heritage site, ie how defence use it, and what buildings are protected from demolishment and neglect.
please take the opportunity to submit a comment, no comments will be interpreted as “no-one cares”!

COMMENTS ON POINT COOK HERITAGE MANAGEMENT PLAN
CURRENT SITUATION
Point Cook is being retained in Defence hands and is intended to be re-populated by the RAAF as a working Heritage Base, however it currently remains largely empty, with more than 60 percent of the buildings vacant with little or no maintenance undertaken on the buildings for many years, well before the 1990’s in some cases, with most lacking adequate roof guttering, downpipes or drainage, resulting in damage to weatherboard cladding, internal timber frames and the base of structures. Defence are “demolishing” heritage buildings by neglect while others face intended removal due to the lack of intended Defence use.
It is understood Defence plans for spending on the site is now deferred to 2015/16 or beyond, and largely limited to inground services upgrades of Electricity, Water, Sewerage and drainage, meaning that many of the heritage buildings have not had adequate maintenance for over 20 years or more since the wind down to closure commenced in 1992.
Appendix E highlights the poor condition of many of the historic buildings and that many of the timber/weatherboard structures have no paint /sealant protection, the guttering/downpipes have failed and permit water to enter the internal ceiling and wall structures and metal roof cladding on many other structures is leaking and overdue for replacement.
It is likely some of these heritage buildings will not survive a further 5 or 6 years of further neglect, and will be assessed as to far gone by then and demolished due to cost or safety issues.
There is an URGENT need for DEHWA to step in and take control of the management of the site and provide immediate heritage funding as undertaken at similar National Heritage sites such as Point Nepean and the Sydney Harbour Trust sites.
SPECIFIC COMMENTS ON THE HERITAGE PLAN
The document has been developed by external consultants ERA Australia, and is quite well done, unfortunately a number of historic buildings on site are at risk due to the low importance ascribed them in this plan, and the consideration of “demolishment” as a “Heritage Management” Strategy, including buildings from WW1 and in the most important heritage precinct of the base – ie the Southern Tarmac
Section 2.5 Future Use
This section discusses the Future Use considerations including re-activation of RAAF Williams Point Cook as a “Working Heritage Base” yet there is no reference at all to the “Underlying Planning Principles” issued as policy by the Parl. Sec for Defence Peter Lindsay in September 2007 and in particular the following:
The future use and management of RAAF Base Point Cook (including the location of Defence functions and activities) is to be cognisant of, and facilitate, public access and use. • Future Defence use of the Base is to have regard to the location of the Point Cook State School and Pre-school. • RAAF Bases Laverton and RAAF Base Point Cook are to be retained in the longer term.• Funding will need to be sourced to undertake the necessary upgrade works to site facilities, to provide for the ongoing maintenance requirements.
The current Defence plans to close off public access and use of the most important heritage precinct on the base, the Southern Tarmac for “operational purposes” , is not consistent with facilitating public access.
The HCMP correctly identifies on page 6 in clauses 2.3.1 Maintenance that “The primary risk to the Heritage Values at Point Cook is through disuse, leading to lack of maintenance, and repairs, consequently resulting in deterioration of building fabric, Unused buildings quickly deteriorate…. results in buildings that are unsafe for use, unfit for purpose, and unattractive as restoration projects, often resulting in demolition as the most viable solution.”
The report notes that 60% of the base is currently un-occupied, and if those buildings remain empty and not required for Defence purposes they will not be maintained, and suffer eventual demolition, the current “blue base” strategy of Defence removes all civilian aviation to the north of the base, and removes any ability for non-Defence use of the heritage buildings, other than the pre-school and State school.
Under 2.3.2 Compatible Use the HMP identifies that “there is a potential for a number of different uses for various precincts on the base, at that the location and types of fences … must be considered carefully to maintain consistency to the original planning concept.”
Under 2.3.4 Security, the HCMP identifies that increased security is being required across Defence bases and that the current museum access may be limited in the future due to heightened security restrictions.
Defence already has a very secure base at Laverton, with no need to support public access for civil aviation or museum visitations, and there is a need to re-think the intention to relocate significant “operational” and security sensitive resources from that secure base to Point Cook, and still be able to ensure significant public access. This issue is more important given the foiled terrorist attacks on Holsworthy Army base.
Section 2.3.4 and 3.1.2 in regards to Security proposes to manage Point Cook in accordance with the latest Defence security requirements, and it is therefore clear that the “operational” activities being proposed for Point Cook are NOT consistant with the “underlying planning principles” and that those principles are not being used as the basis of Defence planning.
Section 3.1.5 proposes a policy of seeking compatible uses for Point Cook buildings and precincts, and the 2003 Point Cook steering committee investigated such options, however the current Defence precinct designs servrely limits civilian use to most of the vacant buildings including all of the Southern Tarmac, and therefore threatens buildings that Defence cannot use (such as building 90 the 1922 Motor Transport Garage or building 108 the Seaplane Jetty) with remaining vacant and being neglected and eventually demolished to avoid Defence spending on buildings it is not using.
Section 3.2.1 Deals with the Southern Tarmac, the most important and historically significant part of the base, with the earliest aviation buildings in Australia, from the pre-WW1 hangars of 1914, the WW1 Hangars of 1917, the interwar buildings from 1919 and the 1920’s, it predates all other aviation related buildings in the Nation both civil or military.
Yet the importance of that precinct is not reflected in its value as a whole, unlike the “heritage Precinct” planned around the married quarters.
While some buildings are listed as Exceptional and high, the group is unclassified at all, yet clearly worthy of being “Exceptional” as a group. In addition the overall intactness of the Southern Tarmac precinct and the future of a number of individual buildings is at great risk due to neglect of buildings due to the lack of Defence use, and the lack of access for Civilian use.
In addition there are current plans by Defence to build new buildings in this precinct, demolish buildings from the WW2 and post war period, and an apparent attempt to try and recreate the precinct back to its 1930’s layout by moving building 210, the historic 1914 Aeroplane Hangar onto the site of the Bellmans when they are demolished. However it is clear that is a “third” and inappropriate site, not a return to the “original” site, and any move will destroy more of the heritage of building 210 and its existing building fabric that any re-siting will “reinstate”.
The HMP must ensure the historically sensitive Southern Tarmac site is managed as a collective precinct, and not naively modified to create a “quasy” 1930’s streetscape at the cost of interwar, WW2 and post war buildings that are just as important to the overall Southern Tarmac story.
The HMP must also ensure that no new construction is undertaken on the heritage sensitive Southern Tarmac site, the heritage values should not be damaged by “Operational” issues that may only be a transient and infrequent use of the precinct in any case.
Defence is seeking to close off the public access to the most significant historic part of the base, the Southern Tarmac. This is assumed “to set it aside to support military flying operations when required, particularly as a contingency to support national security requirements. Such operations would be accommodated as required.”
Yet such operations are very few and far between, but is resulting in many historic buildings on the Southern Tarmac being considered “not fit for purpose, and not required for Defence use” but also not available for civilian use.
In 2008 a wind storm blew off the roof cladding, and caused the western wall of the 1922 Motor Transport Garage (building 90) to fall over, the building is currently left without any protection to its exposed internal structure, and faces uncertainty as to Defences intentions to repair or demolish, yet it is listed as being of “High Significance on page 27 of the CMP.
A letter from the office of Parliamentary Secretary Dr Mike Kelly in November 2009 advised that “a base redevelopment project is currently proposed for delivery in 2013-15, which will address a number of underlying maintenance priorities … however not all buildings will be restored and no commitment can be made to building P90.”
It’s clear that in its current exposed condition building 90 will not be in a fit state to restore in another 3 to 5 years when such funding might become available.
Worse, this Defence reply contrasts with a letter of July 2009 from the Department of Environment, Heritage, Water and the Arts, who administer the National Heritage List and EPBC Act, who advised that “The National Heritage management principles and commonwealth Heritage management principles oblige Defence to protect and conserve heritage values, including ensuring the damage to Building 90 is not being exacerbated by neglecting protection from the elements. The compliance area of DEWHA will be making contact with Defence in respect to this issue.”
Point Cook is the only National Heritage Site remaining in the Defence control and it seems clear Defence does not have the focus or resources to maintain it.
The Draft HMP on page 27 lists the 4 Bellman Hangars on the Southern Tarmac (Buildings 211-214) as being of Moderate significance, and had previously proposed on page 26 that existing buildings of Exceptional, High or Moderate significance should be retained in their present location, yet in this instance specifically recommends demolition as being appropriate?
Of those 4 Bellman Hangars on the Southern Tarmac, 2 are rare examples of the original samples sent out from the UK, (all others in Australia and at Point Cook are locally made examples), but have been slated for demolition . While their uniqueness is well known and even referenced in a public display within the RAAF Museum, it is not recognised at all in the CMP and the buildings are therefore considered of moderate significance and “demolition considered appropriate” as per page 27.
Yet with some refurbishment they would be very suitable for use by civilian aviation, (or support of the infrequent Operational Defence use of the base) as they had previously been used for many years. In fact in 2006 4 long term tenants of the Bellman Hangars were evicted (on claims of the Hangars were unsafe and requiring demolishment – contrary to independent engineering advice), and since that time the Hangars have remained unused and vacant, deteriorating further. This has resulted in Defence foregoing the @$50,000 annual income previously generated, which over this last 4 years could have generated @$200k to fund recladding of the roof’s, and reinstatement of the stormwater guttering and down pipes to avoid ongoing water damage to the building structure.
Clearly the two rare UK built examples would be considered “High” significance not only to Point Cook but nationally across Australia..
An important heritage issue is the WW1 seaplane jetty on the Southern Tarmac, recognised in this report as being of Exceptional significance, and recommending investment of funding to preserve it for use by “relevant user groups” (page 26) , yet Defence has done no preventative maintenance on the jetty for years, and its highly unlikely that without regular public access requirements to the jetty that Defence will provide any funding at all to maintain it as there is no “Defence” use for the jetty.
As explained above, two of the Southern Tarmac WW2 Bellmans are known to be rare examples of the original samples sent out from the UK, (all others in Australia and at Point Cook are locally made examples). this is not recognised at all in the CMP and the buildings are therefore considered of moderate significance and “demolition considered appropriate” as per page 27.
There is need of further work on the HMP treatment of the Southern Tarmac to ensure protection of both the WW1 and later buildings regardless of intended use by Defence.
The Report does not appear to recognise the value of the intactness and “collective group” of buildings on the Southern Tarmac as being the most important part of the base? contrasting table E.14 “Significance of Southern Tarmac Assets” which only lists the 25 various “Aviation” buildings in individual categories from intrusive (1), low (3), Moderate (9), High (7) and Exceptional (4), where as the WW1 and interwar group of 13 married quarters (houses) listed in Table E.16 “Significance of Staff Residences Precinct Assets” are all individually listed as “High” (13) and notated that the it is considered that collectively, the group is of an “Exceptional level of value”??
Point Cook is Australia’s most important AVIATION heritage site, the values that place it on the Commonwealth and National Heritage List is its links to Australias Aviation History, it is therefore beyond belief that the Heritage Management Plan and assessment is that the most “Exceptional” precinct of buildings existing at Point Cook is 13 uniform wooden houses not dunlike those found on early Army or Navy bases un-related to Aviation activities?
Section 3.3.5, Building 72 Former Barracks Store and Office.
This building is currently incorrectly assessed as being of “high” heritage significance and is recorded as originally being sited on the Southern Tarmac, and being relocated twice and having previously been the Barracks Store and Office. However the HMP totally ignores the true significance of this building as the original Flight Office and Casualty building of 1917 from the Southern Tarmac where it was sited adjacent to the Aeroplane Workshops building 95. This building was the WW1 equivalent of the Flight Operations Building or in fact the “Control Tower, with the necessary function of casualty treatment of injured trainees being an equally important role of those early days of flight training, as such it is clearly of Exceptional heritage significance and requires futher review by the HMP.
The Historic Buildings under threat or requiring further review include:
Building 95 – Aeroplane Workshops – 1914 – Southern Tarmac (This building is incorrectly recorded as “Seaplane Hangar” – that label only relates to the rear half of the building built in 1916 in conjunction with the Seaplane Jetty)
This building has a significant heritage value in its front wall cladding consisting of a dent associated with the 1915 crash of a Bristol Boxkite by trainee White, as such the cladding should be seperately noted for management and protection, no specific comment is made in regards to that feature or its future protection?
Building 210 – 1914 Aeroplane Hangar – 1914 – Southern Tarmac
Defence has an un-released strategy (RAAF Base Williams Redevelopment Analysis Report – May 2008) to relocate this building to its “original site” if the 4 Southern Tarmac Bellmans are demolished, yet that is a physical impossibility as the large Seaplane Hangar 101 was expanded over the original site of building 210, being the cause of its relocation to its current site. Any attempt to move it “back” will be destroying history of its current location for the last 70 years, be unable to locate back on its original site to “recreate history” and likely result in much of the existing fabric of the building being destroyed in any such move.
The Heritage Management Plan does not address those existing Defence plans despite the apparant overlapping of their development?
Building 108 Seaplane Jetty – 1916 – Southern Tarmac
Despite being assessed as “Exceptional” there is no intended Defence use of this asset and under their own stated policies, buildings not utilised will not be maintained. Current Defence Heritage base strategy locks the Seaplane Jetty deep inside an intended Defence Operational area, precluding access by the General Public for heritage/tourism, recreational fishing, boating or ferry arrival/departure, or even seaplane joyflights – it is clear Defence itself will have no operational use of the Jetty and therefore this asset will need specific DEWHA funding to protect it from the risks of demolishment by Neglect.
Building 72 Former Barracks Store and Office “School Precinct.
This building is assessed as being of “high” heritage significance and of relatively poor condition, (page 69) and commented “Costs to return the building to an acceptable standard may be prohibitive given the small size of the building” This building was the WW1 equivalent of the Flight Operations Building or in fact the “Control Tower, with the necessary function of casualty treatment of injured trainees being an equally important role of those early days of flight training, as such it is clearly of Exceptional heritage significance and requires futher review by the HMP and urgent and priority funding to be protected.
Building 90 – Motor Transport Garage – 1922 – Southern Tarmac
Despite being assessed as “High Significance” this building has suffered roof damage and has been left without roof cladding since mid 2008, resulting in ongoing exposure to the elements causing deterioration to internal timber frames and structure. –
The Heritage Management Plan does not address the buildings current state or the urgent need for repairs, and those repairs should made a priority in section 3.2.1.
Buildings 211-213 Bellman Hangars C1940 – Southern Tarmac
Two of these Bellmans are known to be rare examples of the original samples sent out from the UK, (all others in Australia and at Point Cook are locally made examples). this is not recognised at all in the HMP and the buildings are therefore considered of moderate significance and “demolition considered appropriate” as per page 27. clearly the rare UK built examples would be considered “High” significance not only to Point Cook but across Australia..
It is therefore clear many of the historic buildings on the base, and particularly on the Southern Tarmac will be left unutilised, and therefore targeted by Defence for demolition, this is the recommended policy of the RAAF Heritage Advisory Council report of 2006, and a theme maintained through into the HMP.
The current Defence layout and implementation of the “working heritage base” is creating great risk to the ongoing preservation of the historic buildings on site, there needs to be a re-think of the Master Plan for the Heritage Base in light of the National Heritage Listing and in compliance with the Government’s direction in its underlying planning principles of 2007 for “the future use and management of RAAF Base Point Cook (including the location of Defence functions and activities) is to be cognisant of, and facilitate, public access and use.”
There is an URGENT need for DEHWA to step in and take control of the management of the site and provide immediate heritage funding as undertaken at similar National Heritage sites such as Point Nepean and the Sydney Harbour Trust sites.
In 2000 the Federal Government set up the Sydney Harbour Federation Trust with funding of $90M to manage, preserve and develop public access and usage of 6 former Defence sites at Middle Head, Georges Heights, North Head, Woolwich and Cockatoo Island.
A more direct comparison is the creation in 2004 of the Point Nepean Community Trust with funding of $48M to manage, preserve and develop public access and usage of the former Defence Point Nepean site, inclusive of $31M to restore and develop the Quarantine Station / Norris Barracks buildings.
While the “Working Base” model is intended to retain an ongoing Defence relationship with the site, a worthwhile objective, it has effectively left the site and important buildings in limbo for the last 6 years, awaiting future funding that may never come, or be too late.
In the 6 years since being placed on the CHL in 2004, and subsequent replacement of the Trust outcome at Point Cook the only significant heritage building maintenance undertaken at Point Cook was to replace the asbestos roof on the 1914 Aeroplane Workshops (building 95), and 1927 Seaplane Hangar (building 101), many others are suffering leaking roof’s, leaking or non-existent guttering and down pipes, flaking or missing paint, resulting in the timber frames and weatherboard structures rotting rapidly.
A revised Master Plan layout of precincts and entry methods focused on public access, together with a re-visit of a Community Trust model under a lease from Defence, to manage the public areas, and maintenance and civilian use of surplus heritage buildings could access similar heritage funding to that gained for Point Nepean, and provide a stable and continuous management model for this important National Aviation Heritage site.
The Historic buildings of Point Cook cannot afford to await another 3 or 4 years for Defence to allocate some funding for maintenance, or for the buildings to collapse to neglect, action is required in this Centenary of Australian Aviation, to ensure Point Cook’s heritage buildings will survive for the site’s own centenary in 2014.
.
I would be surprised but delighted if it was restored to fly, with a second one on gate guard duty also in the same country, Argentina is the only place such an outcome could ever occur with any confidence.
By bringing the second one in from the cold to the National Museum to allow for a spares ship and one restored as a static exhibit, the better of the two could therefore possibly restored to full airworthy condition?
It would then perhaps be quite a National flag waver for Argentina within South America with possible airshow/PR visits into the USA?
We are all allowed to dream smiles

Well theres nothing like some photos to confirm a rumour smiles, its a pity this one was recovered and scrapped, that lot sitting at the bottom of a fresh water lake for 60 years would still be likely to form a viable static restoration even today.
So that still leaves the question – where is the well known wreck in a deep lake mentioned above, and what survives?
My quoted post above still refers to TT’s original post and the suggestion one does still survive in a lake, is this true, or confusion rumours based on this recovered wreck?

Signed up last week – but I understood it was another Upkeep being recovered! :confused:
The Highball topic reminds me of an early work encounter with a storeman back in 1977 / 78. He was always prone to exaggerate anything he told you, so when he told me of ‘Highball’ Mosquitoes being shipped to the Far East on HMS Fencer and HMS Striker – I immediately questioned the validity of his story!
I was suitably put in my place the following day when he showed me his pictures from on-board, with all the aircraft stored on deck. An interesting aside was that one of the vessels was sunk and that should have been the one he was on, but he had ‘suffered’ a very lucky mix-up with his posting!
This would be the RAF 618 Mosquito Hiball Squadron that was brought to Australia in January 1945 as part of the intended tiger force, one of their training aircraft, a FBVI still survives today in Australia.

“From Wiki”
For this role 25 Mosquito B.Mk.IVs were further modified:
Each aircraft was equipped with Merlin 25s, adapted to provide peak power at low altitudes, driving four-bladed Rotol propellers: these propellers had narrower blades than the standard three-bladed units, meaning that the engines would rev up faster and respond quicker to throttle movement, factors vital in the limited length of carrier take-offs.
Longer intakes under the engine cowlings were fitted with tropical filters.
The undercarriage legs were made of heavier-gauge metals and the wheels were fitted with the twin brake units of FB Mk VIs.
The rear fuselages were structurally modified with a special internal longeron and reinforced bulkheads designed to take the additional loads imposed by carrier landings: an additional bulkhead (No. 5a) was fitted.
Externally a “V-frame” arrestor hook was fitted. The “snap gear” which released the hook was operated by a Bowden cable from a lever mounted on the cockpit port side.
An access hatch was moved from the starboard rear fuselage to underneath, and an extra longitudinal stiffening strake, identical to that already fitted to the starboard side of production Mosquitos, was fitted to the port fuselage.
The tailwheel fork pivots incorporated end plates to avoid being caught in the arrestor cables.
Armoured windscreens were fitted, along with hydraulic wipers.
Three PR.Mk.XVIs, which were to be used for reconnaissance duties were also fitted with the four bladed propellers and fuselage modifications for carrier operations.
These Mosquitos were transported to Australia on board the carriers HMS Fencer and Striker, arriving on 23 December 1944. In order to keep up aircrew proficiency and safeguard the modified Mosquitos 12 disassembled FB Mk VIs were also sent, arriving in Sydney in February 1945. These were reassembled at de Havilland Australia’s Mascot factory. Once again, because of political-strategic infighting between the British Pacific Fleet and the U.S. military, the unit was never in action, and was disbanded at RAAF Narromine in July 1946.The converted Mosquitos were stripped of all military equipment and sold off. The sole surviving 618 Squadron Mosquito, an FB. Mk.VI HR621, is currently undergoing restoration at the Camden Aviation Museum, NSW.[1]
Australian deployment
In January 1945 618 squadron was deployed to Australia, as Japanese targets for the Highball weapon were still available there. Arriving on 23 December 1944, the aircraft were sent to Fisherman’s Bend aircraft factory for reassembly. Training began at Narromine in February 1945. A detachment was sent to British Pacific Fleet base at Manus Island in March, but the squadron was unable to go into action against Japanese shipping, mostly because there was no target left in the area anymore. The squadron was therefore disbanded (officially) at Narromine on 14 July 1945.[2][

From the photos its clearly hand operated (twin grips and thumb triggers) and swivel mounted for tilting, I doubt it is for a vehicle but its certainly not for the fixed nose guns etc of a P39 or P63.
actually google is your friend>> see here – it is quite a famous wartime development of a recoil damping device for gunners in bombers such as B-17s? claimed or credited with increasing the hit rate of the gunners?
Smiles – that will teach me to be slow to post while I google and paste it seems others answered the question in anycase

I think we should be going one better and trying to identify a downed(preferably ditched) variant that perhaps could be restored at least to museum condition.
From all of your reourcse has anyone got a clus on how I could start this research project?
Thanks
No the serious missing link is a satisfactory way of accessing drawings or at least knowing for sure what drawings exist [if any ]and this applies to all aircraft. You can dredge up any old wreck but you still need a set of drawings to work out how to re-make parts.
Graham
I think if there is a “recoverable” Stirling still out there then it forms the priority in saving the type from extinction, however that doesnt seem to be the case and instead a hybrid replica from drawings and restored/replicated wreckage seems the likely path.
I’m not sure the Stirling drawings survive in their entirety? I thought that was one of the problems facing the project?
However having purchased over 4000 drawings from a manufacturer of a WW2 type to support a restoration, I would disagree that access to drawings is better than finding a restorable wreck. Even if the wreck is beyond preservation, its intact structure is likely to form a better pattern for templates than thousands of drawings.
Manufacturers drawings are NOT drawn for one off cottage industry manufacturing by modern restorers or museums, and quite often leave fabrication details to the factory floor to resolve with jigs etc, while it is obviously possible to dimension from the drawings, often a pattern item allows for a 3-D jig to be constructed around the piece and then raw materials to be re-engineered from dimensions taken directly from the pattern.
In most cases the pattern will yield some component/casting/fitting that is re-usable – particularly if the outcome is to be static. In the case of castings, a pattern example can simply be duplicated from a sand casting process where as a drawing requires a plug to be crafted to then form the sand cast.
If theres a choice between recovering a complete “wreck” and finding the drawings, I vote for the wreck – smiles
