7/25/17 - This is an original Police issued Luger magazine. The base of the magazine is aluminum and stamped with a "*K" proof, which is a known Police stamp. There is also a "1" and serial number "6724". This Mauser magazine is in great condition with minimal wear on the exterior of the body. There is some minor aging and use wear, but no rust or pitting. The spring is strong and firm, but when slowly released upwards, it can get caught about 2/3rds of the way up the tube. Please see photos. This is probably an easily repaied magazine, but priced as-is. Guaranteed original and authentic.
