At first, thank you very much for all your replies and the interesting discussion.
I took some photos and I'm sorry for the bad quality, the lighting wasn't good. In the photos you can see the fxo magazine and the 122 magazine which I got with my new P08 S/42 1936. The pistol is matching, just the magazine is not.
What do you think about the fxo magazine? I guess it's a fake.
Greetings,
Stephan
