7/7/17 - This is a WW2 era production Luger magazine. The magazine is serial numbered with a "+" sign and stick winged eagle 63 proof stamp on the aluminum base. The tube is blued and excellent with no rust or pitting. The spring is strong and fully functional. There is some very minor wear on the left side of the frame near the base of the magazine. This is only a small area of bluing loss. Guaranteed original.
