A few days ago I spotted someone who was interested in
Julius Bucklers autobiography of his wartime career. Today I typed in his name on the computer in the library of my university. Et voila! There it was. A 1939 version of the book in German. I also found a 1933 version in German of "Der Rote Kampfflieger" as well as a photobook by Udet detailing an expedition into Africa which he accompanied.
I don't remember the name of the person who asked about Buckler but he/she can contact me through the forum. I cannot do much with it, being a librarybook of course, but if there's specific info required, let me know and I'll keep an eye out for it.
Kind regards,
Reinout
