Typhoon Ia or Ib

[MW Giles]

Does anyone have a listing of the Typhoons in the batch R7576 to R7923 and which were built as Ia and which as Ib?

I have the Putnam "Hawker Aircraft since 1920" and Air Britain "RAF Aircraft P1000-R9999" but neither are of any help

Regards

Martin

They were listed in the Air-Britain Typhoon File which I compiled more than 30 years ago. I'm afraid some of the histories contain errors - we've learned a lot about the vagaries of official records, particularly the Forms 78 and ORBs, since then. The listings of IAs were taken from the Forms 78 as these are the only existing source known to me which notes them.

Thanks for providing a source, I have been looking for some time now

I will look out for a copy, sorry there are no royalties from the second hand trade

There were no royalties from Air-Britain either in those days! If you can't find a copy drop me a line.
