Thank you for your kind offer, Przemol!
What I am looking for is a recommendation for a book (or two...) about the Polish Air Force during the period of the Post-War-Wars, that is planes, profiles and the historical background. As I do not know any polish except for "dobry den" and "dzenkuje", I would prefer books written in english...
By the way: Is that Polish Gotha G IV on your building-list? I would be most delighted to see that...
Best regards
Richard
