5/9/18 - This is an original WW1 era Luger magazine made and marked for the German navy. The magazine has a wood bottom with concentric circles on the "ears". The right ear is chipped - as shown in photos. The base is serial numbered 8209x with a crown/M navy proof stamp. The spring is strong and functional. The magazine frame has discoloration throughout. Mostly surface wear and beginning signs of rust/pitting, but there's no rust or pitting yet.
