1/31/18 - This is an original, rare, and early WW1 Navy Luger magazine. The bottom of the magazine is wood and in excellent condition. There is a crown/M Navy proof stamp and number "621". The serial number runs vertically up the magazine base, which is an earlier more desirable style. Either side of the wood bottom has the Navy-specific concentric circles. The aluminum frame of the magazine has some minor spotting of dark wear, but there is no rust or pitting. The spring is strong and fully functional. Guaranteed original and authentic.
