I was thinking DVII.

The important think to remember about the DH props is that, lets say a ‘1,000 Series’ refers to the size of the blade root only. Thus a ‘1,000 Series’ could be for a DHGQII with a Number 1 SBAC spline, or a DHGQ30(etc.) with a Number 2 SBAC spline.
I can’t speak with regard to the other manufacturers, but the list below seems to indicate a similar arrangement.

As far as I understand it:
Bracket types:
1000 ?
4000 No4 shaft, D shank
5000 No5 shaft, E shank
6000 ?

Hydromatic:
4000 No6 shaft, D shank 4 blade
4500 No5 shaft, D shank
5000 No5 shaft, E shank
5500 No6 shaft, E shank
6000 No6 shaft, shank ?

The Spitfire photo you linked tends to back up that the 4500 is a D shank hub, because there are 9 barrel bolts.

Post war they went over to a completely different numbering system!

Do all of the original drawings for the Wellington still exist…. ? One rather presumes that Brooklands had access to drawings when they renovated theirs….? If there are no drawings, then that really does make it a very impractical project. If the drawing have survived, it’s all down to money.
Finding an ID wouldn’t be that hard – look at how many of certain types have been resurrected from a handful of original parts.

Criminal behaviour is just that. However, one has to chuckle at the rank stupidity of some ‘collectors’. What are the chances of large amounts of one special-interest all turining-up in one place at one time…? Obviously pretty slim. Doh…. The issue is really driven by the high prices paid for ‘collectibles’. Now I confess to buying old junk – but I have uses for it 99.5% of the time – and I know for sure what it is. Just occasionally, I’m buy ephemera – if it’s germain, genuine – and cheap. The reality is that collectors are often hoist upon their own petard, as someone alluded to above. Lets face it, most of this stuff is basically just junk, if we ascribe absurd values to it, we are simply encouraging the kinds of fraudulent behaviour described above. Still, one can’t help smiling…

As a contrast to accounts of these a/c flying in preservation, many years ago I fead some really fascinating accounts of ‘109’s being used in combat by the Israelis post 1945. If I recall correctly, they flew not only real ‘109’s, but Buchons as well as the other post-war revamped – (Was it Hungarian/Turkish…?) – non-DB-powered version, as well as many ex-Allied types. The Israelis were non-too keen on the offspring of the ‘109. The article might have been in an issue of AM from about thirty years ago. Maybe someone here can pinpoint the article…?

Ah yes, the Albatross – sublime!
