A friend just mailed me pics of a new to him gun. Specifically, a P38 with the markings "BYF43" and "135 with eagle and swastika". He says the first mark means it was made around 1943 and that the second marking means that it was approved for combat. He thinks this weapon was issued to officers of high rank but isn't sure about that. It looks to be in exceptional condition considering it's age. I suggested he have a smith check it out before firing it and also suggested that it might be better used as a collector's item than a regular range/SHTF gun. Considering that this gun is over 65 yrs. old, can it take modern ammo without damaging it?
