Cannot match those numbers to anything Whirlwind. The spares list gives 27K/51 as the ref for the pitch control receivers, that is all I have, though am looking for photos.
Unless the Third Reich gave it as a formal gift to the landowners I think it counts as a fly-tipped item :eagerness:
He wishes! But then again, owning a fabric-winged Hurricane is quite Rock and Roll, I guess.
Elements of Paul Rogers’ Hurricane at Gransden are from one left in a ditch during the retreat from France. It was Paul’s father, an 87 Squadron fitter at the time, who remembered exactly where they’d left it.
Ask Emily.
They exist in the national archive as well, volume 1 of the AP (No. 2215A) is file AIR 10/3051, filed under ‘engineering, descriptive’ but I figured that asking Westland might get you some drawings as well. They also exist.
Here you go. If you really need to know, any original data and drawings will be at:
Agusta Westland Archive

Emily is very helpful, but also really busy right now with the 100th anniversary celebrations, so don’t worry if it takes a while to hear..
Topspeed, the problem you are having is getting all of your data from amateur websites. Have you consulted the pilot’s notes yet? There are primary sources out there to uncover, getting in a spin about conflicting data in secondary sources, the worst of which is the internet, is a blind alley.
No.
Three-views are not the same as factory drawings. They were published in all kinds of places at the time, including aircraft recognition charts, AP’s (you might know these as ‘pilot’s notes’), even magazines. They would be based on official three-views released by the manufacturer. Anything that follows after is either faithful to these or not, but ‘fake’ is the wrong word for any inaccuracy.
The drawings required to accurately reproduce an aircraft are something completely different from such artwork.
Absolutely! It’s also odd how in – what – 70 years, so much knowledge has been lost forever. In another thread the topic drifted (my fault) on to preservation of drawings by companies, or the lack of it. De Havilland did not keep any blade design drawings at all, despite having a whole department dedicated to producing propeller blades for years.
All that are left are fragmentary graphs of thinks like AF, twist and thickness compiled by the A&AEE and held by the FAST library. So, nobody knows very much about the shape of blades used by the thousand within living memory, without measuring surviving artefacts.
This missing information includes which profiles were copied from which Hamilton blades (if any) …Or maybe they all were, and there were no actual de Havilland drawings in the first place? All that would then be missing would be the ‘smoking gun’ table of equivalents.. or a newly-created database from surviving blades that might establish matches. As I say, crazy that this would be necessary within 70 years.
But I digress
3D40 is bracket, 23D40 is Hydromatic!
Thanks Moggy.
Thanks Moggy.
How many sets of factory drawings for different aircraft have been lost at least partially by fire, tempest & flood?
Too many to be simple chance in my limited experience.Perhaps the high cost of micro-filming and the great bulk of a full set of drawings explains part of it.
But I feel other factors were involved almost as though it was a deliberate decision to remove & forget the past.
Does anyone agree?The Whirlwind & the Welkin seem to be examples relevant to this thread.

Interesting.
In the case of Yeovil it does suggest a carelessness, putting the drawings close to the water table. And certainly when things started getting floody no-one said ‘Quick, save the drawings’. In fact it wasn’t until 1970 that the detritus was sorted and the surviving sheets archived, with copies sent to the new RAFM.
But I think it was just a lack of care. C0ck up rather than conspiracy. I wonder how long any bits of paper with no perceived value survive in a commercial / industrial environment like a factory airfield, on average.
If you are using factory drawings you’d need to 3/4 scale everything, including the pilot… or do you mean a model?
Why not build a full-size Whirlwind? Just as crazy. Can’t remember what year -1949, maybe?
Most of the drawings were destroyed by flood in an underground store on Yeovil airfield. Some (very few) survive, I THINK, at the Westland archive, still in Yeovil.
Ach nein, 3D40 or 3D50 🙂
