Hawker Engineering Blueprints

I have recently aquired the following 1920s original Hawker factory blueprints when purchasing some vintage car related stuff. Cars are my main interest so
I’m looking to sell the blueprints. However, as I know little about vintage planes I have no idea what their interest would be and where best to advertise them. I would like them to go to some one who knows and appreciates what they are but I would also like to recoup some of the money I spent on the car parts. Any advice would be appreciated. All the blueprints are of approx A1 size and show overall / structural view of the planes. They therefore have a decroative value. They are worn, stained and slightly faded with the odd engineers scribbles on the back as you would expect. They include:

Sopwith Hawker HawfinchJupiter MK V1
Drg No. 5429
26/11/26

Sopwith Hawker Night Bombing Land PlaneDrg No. 10284
8/11/27

Mystery Hawker Bi – Plane (whole plane title has been blanked out of print)
Drg. No. M193
9/2/1927

Horsley III Single Engine Day BomberRolls-Royce Condor
Drg. No. E8610
10/5/26

Dragging this thread back from the dead. Does anyone know the final fate of these bleprints?

Of all the drawings I think the most interesting is the Horsley layout. I reveals a dual control facility for the gunner, which I thought had died out with Great War types.

It hadn’t, as shown, John. See the next Aeroplane’s Aircrew for another example of a occasional dual control type in post-Great War RAF use. 😉

I wonder if the seller did get them copied and ‘donate’ the images to a museum. I’d bet not.

‘blue prints’ like that should be stable under scanner light, but best not exposed to constance dauy light ie in a picture frame. Getting the creases out could be an issue, not sure how resolve that ?? The scanned image can be ‘reversed’ to give a black on white image, and print, depending on the time and effort spent by adjusting the resolution some of the worst, tears and creases could be removed.

I would suggest you try and get the crease marks reduced if possible before scanning.

I wouldn’t suggest doing it yourself with an iron though, but seeking professional advice.

Another thought, are blueprints light-sensitive? The scanning process uses a powerful light – make sure the process won’t degrade the originals.

Thank you for posting the photos.

I suppose you have the David Thirlby book The Chain Drive Frazer Nash.

Hi James,
You could try the likes of Kall Kwik printers or Staples, the office supplies people, but be sure to ask that you receive the CD files as .pdf or .dwg format, prefferablely both. Alternatively ask at a local Architect or Consulting Engineers office both are likely to have the necessary equipement. Be sure to emphasize that the copy is for personal use, I am not sure about copyright issues but some shops can get fussy about such things.

Thanks for your forum posting. Cadman – I think scanning the blueprints as you suggest is an excellent idea. I will try and find a local (cornwall) company to do it.

Corrr.. you lot know your planes! John Aeroclub – you are right, it should be ‘Night’ bomber so I’ve edited my posting.

I go to Brooklands occassionally so I well definitely check out their archive – I always forget its plane connection..

You might consider getting them proffessionally scanned and reprinted to A1 size. (PM me if you have any questions about this as I may be able to help)This way you can keep a copy for your own interest, sell the originals and if you are so minded offer the copy CD to other interested parties.

Brooklands Museum does have an archive. Presumably this will include Hawker records and drawings?

The mystery biplane looks like the Hawfinch fighter prototype built to F9/26 but has single-bay rather twin-bay wings. I believe the Hawfinch was used at the R.A.E for investigating different wing profiles so perhaps this is a modification for them

The project types are rarer than most, and therefore more historically interesting, but not ‘rare and collectable’ for (big) cash, I’d suggest. It would be nice to see them donated to somewhere that would enable public access to them.

Interestingly Frazer-Nash designed the Gun turrets on some Hawker planes so I wonder if that could possibly explain how these drawings came together?

True, but I doubt the link, the FN turret line being later than these types. The first FN turret went up in a Hawker Demon in 1934. Get a copy of British aircraft armament Vol 1 for the history of the FN turret business – it’s an interesting story.

HTH!

These are quite interesting as I don’t think these drawings exist elsewhere. At least for the Light Bomber which I think should be Night Bomber B19/27 of which a project drawing was done, The Mystery (single bay) biplane is again an early project/concept drawing for, I think, the Heron or possibly the F20/27.

The Horsley especially and Hawfinch are better known and recorded.

John
So you like “Chain gangers”.

James,

Spec 19/27 was for a night bomber that was eventually filled by the Fairey Hendon and Handley Page Heyford. This aircraft would have been Hawker’s tender.

Thanks for your replies and emails. I have just photographed them and uploaded them to flickr. I bought them in a mixed auction lot – included were what appear to be some original factory 1924 / 5 Frazer Nash car drawings. These were what I really wanted as I ‘m mad about Frazer Nashs and GNs!
Interestingly Frazer-Nash designed the Gun turrets on some Hawker planes so I wonder if that could possibly explain how these drawings came together?
Anyhow, I would love to know a bit more about them first before parting with them – especially what the identity of the un-titled plane?

No idea what they are worth really,depends who is after them and what you are want for them.One man’s trash is anothers treasure and vice versa.You must have an idea what you need to see for them.I know someone who is into Hawker types,so let us know a price and we can go from there.Cheers
