I believe I have seen this collection, or part of it, some years ago.
I remember going to an RAF Air Display at RAF Waddington in the nineties and one of the hangars was full of model clubs and traders - I recall chatting to John Adams of Aeroclub, whom I usually saw at the Scottish Nats.
Under a big bomber a modeller had set out a table with scores of these jewel-like 1/72 scratchbuilds of pre 1914 aircraft. I remember a long conversation about techniques and joking about the comparison with the real Vulcan under which he sat. His age would have been right for the article.
Looks like he continued adding as the collection didn't include the big Ilya etc.
I hope a museum acquires these are they are a unique history of flight pre-war.
