Hello Denes,
I'm a founding member of the Austrian Aircraft Historians (Österreichische Flugzeug Hisotriker) and Schriftführer of this reg. association, of course I've all the magazines since 1975. Look also at our website
www.oefh.at. My special interest is the aviation between the wars in Austria.
Fiat Cr 20 was an article in two numbers in 2008.
Sorry to say but it is not clear which Chirris were sold to Hungary.
Best wishes,
Harald
