6/29/17 - This is an original Mauser model 1934 magazine with a Kriegsmarine proof stamp designation. The base of the magazine is stamped "N 8093". The base is also stamped with a Mauser banner. There is some minor wear on the base. The tube is in great shape thought with no major issues, and only some minor bluing loss. The bluing overall is excellent. The spring is strong and fully functional. Guaranteed original.
