7/26/17 - This is an original WW2 era production Mauser Luger magazine, with a rare blank aluminum base. The base is all original and has no signs of being ground down or altered. The frame is blued and in excellent condition. The left side of the magazine is "fxo" stamped with two eagle/37 proofs and a "P.08" stamp. The spring is strong and fully functional. These are very hard to find magazines, especially in this condition. Guaranteed original.
