I have a P 08 1939 42 , bottom of the magazine marked 63 + w, and the right side of the pistol marked two times 655 and an eagle with swastika. All serial numbers match , including magazine .Is this an interesting variation, or is a common one? But the upper dug up relic in the picture is still a mistery for me.. More comments here
