12/19/18 - This is an original Mauser eagle/63 proofed Luger magazine from WW2. The magazine is in excellent condition overall with minor surface wear that almost looks like residue on the tube. There is almost no bluing loss and definitely no signs of rust or pitting. The aluminum base is stamped with a scarce two-digit serial number. Also has an "s" suffix and "+" sign. Below those markings is the stick eagle 63 proof stamp. Strong spring, fully functional and guaranteed original.
