Just to inform you about this excellent new book by Csaba Becze on the Me 210 in service with the Royal Hungarian Air Force. The author has has gone to great lengths to compile the service history from virtually nothing and this book contains never before published photographs and narratives concerning flight training in the RHAF.
I hope to tempt the author over here to tell you more about it soon.
And for those worried about the fact they can't read Hungarian there is a large synopsis of the book in English within. And the photographs alone are worth a thousand words each.
