    RE: Technical Teaser

    Hi Chappies, it’s uncle KeithMac. Christer has pretty much answered Halibags question on the Hercules, so I’ll not steal his thunder. I’ll only add that it’s 1 then 10 because the crankwebs are at 180 deg to one another. As for the Twin Wasp, it works on the same principle. The Gannet however is not a piston engined aircraft! It has an engine called the Double Mamba. It is in fact two turbopops independently feeding power to a gearbox, which output on co-axial shafts. The props rotate in opposite directions to cancel out torque reaction on the aircraft. Both engines are completely independent of one another and can be shut down and the props feathered separately. Hope that’s cleared up that little question. Christer,you talked about Hydraulic Lock, Ill answer that separately on another post.

    RE: Technical Teaser

    Hi Christer, yes I do remember or discussion on the relative merits of sleeve and poppet valve engines. You’ve obviously been hard at work on the radial engine. What have you been using as a reference work? If theres anthing I can help with, fire away. That’s what these sites are supposed to be for are they not!

    RE: Technical Teaser

    Christer, You cracked it, well done, go to the top of the class, I can see I’ll have to make them more difficult in future, how about a 28 Cylinder, four bank radial ?. On second thoughts, perhaps not!!!!

    RE: Technical Teaser

    OK Halibag, now your cookin’. You know the four stroke cycle, that’s where to start! Remember it takes TWO revs of the crankshaft to complete your Suck Squeeze Bang Blow cycle. I know you know the answer!!

    RE: Technical Teaser

    Halibag, you little rascal, you don’t escape that easily. What the other engines are doing has no effect you know that! The nationality of the engines makes no difference either, japanese and german pistons know how the engine works. But i’ll concede the point on direction of rotation. So it’s clockwise viewed from the front of the aircraft, now get on and find me an answer!!!!!!!

    Hi SADSACK. No Comet at Lossie. The only Comet in the area is a battered chunk of fuselage at Kinloss which we used for battle damage repair practice during the days of TACEVAL’s. I’m not even sure of it’s identity!

    RE: Gate guards

    Some info on the Lossie Bucc. The Lossiemouth Business Association is currently in discussion with RAF Lossiemouth about the possibility of opening a visitor centre at RAF Lossiemouth if funding can be raised. My last information which came from a senior officer at lossie, was that the Bucc is earmarked for the visitor centre if it gets the go ahead. For the moment it is in storage at Lossie.

    RE: WW2 MU numbers

    Hi Moggy, Afraid I don’t know of a complete listing but 19 & 32 MU’s were at St Athan and 27MU was a Shawbury, 389 & 390 MU’s were at Seletar, Singapore.

    RE:

    Hi Martin, the advice on the part no. might have been good if the seat was aircraft specific. By the look of the numbers it was not. Prior to the intoduction of NATO Stock No.s in the 1970’s All RAF aircraft had what was known as Sect/Ref numbers which consisted of an alpha numeric code i.e 26DD/ and a number. The code uniquely identified the aircraft, and the number identified the part. However such items as engines, props, fuel tanks, radios, instruments, seats, harnesses, guns etc which were not aircraft specific were given section/refs in a different series. Your seat most probably falls into this category and could have been fitted to any one of a number of aircraft types. I think it will be very difficult to pin it down to a specific aircraft.

    RE: Tracing a pilot

    Sorry! Should have thought to include the RAFA Website, It’s http://www.rafa.org.uk/intouch. They charge a fee for non members, but I honestly think it’s your best option. PMA Innsworth won’t help, it’s against MOD policy.

    RE: Tracing a pilot

    Hi again Halibag. It’s not Mod policy to release details of service and ex service personnel to anyone other than relatives and next of kin. However many ex RAF personnel are members of the RAF Association. They publish a magazine called “Air Mail” which has a section for tracing old friends, sqn collegues etc. Suggest you try that method, I’ve used it in the past and been successful.

    RE: Re-enactors, Actors and medals

    Hi Halibag, No I’ve no problem with the wearing of medals in the circumstances you describe, just the dishonest wearing of medals for self glorification.

    RE: Re-enactors, Actors and medals

    Hi Halibag, I’ve just retired after 39 years in the RAF, so I suppose I’m a “veteran”. Firstly actors. You can’t make a film about the military without having actors in uniform. Generally speaking the researchers get it right and the uniforms are OK, but I recently saw a film starring Tom Hanks playing a wounded RAF Mustang pilot in Italy during WW2. In some scenes he was in correct Flt Lt uniform, in others he was wearing an airman’s uniform with incorrectly applied rank insignia. To make things even worse he had a collar attached shirt, an item of clothing not issued by the RAF until the late 1960’s!! Minor points, but irritating if you know it’s wrong. (The markings on the Mustang were also wrong! Then there are re enactors, again I’ve no real objection provided they keep it accurate and conform to the regulations, for example short hair and no visible jewellery to give but 2 examples. Again the uniforms should be worn in a controlled environment and not just worn to “show off”. As to legalities, it is illegal for anyone not serving in HM Forces to wear the current pattern uniform. There are also strict rules governing when Serving Personnel can wear uniform when off duty. These rules were introduced to prevent servicemen becoming terrorist targets. Having just retired, I can no longer wear any of my uniforms, but can wear my medals on specific occasions. They were earned, and I would be very angry to see them worn by anyone who had no entitlement. My uniforms have been donated to the Museum of Flight at East Fortune, if they can make use of them, then that’s the best place for them.

    RE: RAF’s 28 sqn

    Hi Neilly. The book’s good for tracing locations and movements of Squadrons, and has a lot of good background information on Squadrons. But it’s a book about Squadrons as opposed to aeroplanes, so you won’t find a lot of Tail Number/Sqn info in it. Try and get your local library to get a copy, then you can make up your own mind if you want it. I often get my local library to get books for me (it’s what you pay your council tax for!) If you still have problems get back to me and I’ll extract the info you want and E-Mail it to you. Incidentally I was with 28 Sqn at Kai Tak and Sek Kong from 1977-79, that’s why I noticed your post.

    RE: RAF’s 28 sqn

    A good source of info is Wg Cdr C.G.Jeffords book “RAF Squadrons” ISBN Code 1 85310 053 6 published by Airlife Books. On Page 34 you’ll find a list of movements and equipment changes.
