7/18/17 - This is an original Mauser Luger magazine, most likely made during 1938 or 1939. We can assume this due to the early pre 1940 style aluminum frame. Additionally, the base of the magazine is stick wing eagle 63 proofed, which is a post 1936 proof stamp. The magazine has some light discoloration but no rust or pitting. The spring is strong and has a smooth action. The base is serial numbered and proofed, all in excellent original condition.
