8/24/18 - This is an original WW2 production Simpson Luger magazine in mint condition. These extremely rare magazines are very difficult to find in this condition. The magazine has excellent, all original bluing almost completely in tact. The aluminum base is unmarked except for two eagle/6 Simpson proof stamps, and a + sign, indicating this is the spare magazine. There are no signs of this magazine EVER having a serial number. Super rare! Guaranteed original an fully functional.
