AJ, I was doing some research for my next book and came across a reference which said
>" The war had a direct effect on Skybirds, as Holladay's showroom and warehouse were bombed in 1940, necessitating a move of premises. In 1942 production of toys or models containing metal parts was forbidden, to conserve strategic materials, and production of Skybirds ceased.<
there is also a list of all known Skybirds.
This said, Skybirds could have produced the model directly for the government, they certainly had the know-how, workmen, and machinery.
BTW, The material was in a book review on Skybirds written by the late A G Sinclair. I have a copy somewhere, and I knew Mr Sinclair, even visited his collection at his Wimbleton, UK home a long time ago. He was a bomber pilot in WW2, flew one of those uniquely British concepts - a single pilot, 4 engine daylight bomber. He was one of the few that survived and the first and only combat pilot I ever knew who openly admitted he just hated every minute of it. Just the opposite on my own combat experiences.
