12/13/17 - This is an original pre WW2 production Simson Luger magazine. The magazine is very early, and you can tell from the lightly yellowed finish on the magazine frame. The frame has no rust or pitting but there is some light surface wear. There's also a very small dent on the left side of the magazine (non-indicator side near the base). The base of the magazine is serial numbered with two simpson eagle/6 proof stamps. The spring is strong and fully functional. This is a very rare and desirable Luger magazine!
