8/3/18 - This is an original WW2 production FXO Luger magazine. The magazine has a blued fame and an aluminum base. The base is unnumbered, which is very desirable. No signs of polishing or alteration. The frame has some normal bluing loss, but no rust or pitting. FXO stamped with two eagle/37 proof stamps. The spring is strong and fully functional. Guaranteed original.
