Good evening skytrain,
Busy afternoon and no time to play, I've just been looking at Hirth and was about to ask, so thanks for confirming!
I've not been able to find your drawing, has it got retractable U/C ?
I wondered if it was the Hungarian Samu-Gednczy SG-2 of 1949, I can only find an artists impression and it has some features, but apparently it has fixed gear and the canopy looks wrong!
There was also a couple of Spanish trainers, but again only impressions.
Was it pre or post war?
