At eBay
here is a photo of what I think is a Cierva C-19 (perhaps Focke-Wulf C-19) autogiro. I am aware that this was produced in a number of nations and flew pretty much throughout the world. There are no codes visible on this photo, so no obvious solution to the nation of use. But there is an emblem. This may not be an easy one, but can anyone offer further information on this one.
Cheers
Ian
