7/18/17 - This is an original WW2 Mauser S/42 stamped Luger magazine. The magazine has an aluminum frame that was never blued (earlier variation), and an aluminum base that is stamped "S/42" as well as serial numbered "9418". The magazine frame has some minor discoloration throughout, but this is all normal wear. There is no rust or pitting. The spring is firm, and pushes down with strong resistance, but should still function properly especially after a little oiling. The base is in excellent condition. Guaranteed original.
