7/7/17 - This is an original WW2 production Luger magazine. The magazine base is aluminum with a serial number, "h" suffix, "+" sign, and an eagle 63 proof stamp. The serial number is oddly upside down. The magazine tube is blued and in great shape, but there is some minor residue/surface wear on the tube - we try to show this in photos. The spring is strong and fully functional.
