10/19/17 - This is an original WW1 era Imperial Navy Luger holster. These holsters are extremely scarce, and are characterized by the "M" over anchor stamp. This stamp is next to the maker stamp under the top flap on the main body of leather. There is also an imperial eagle WaA18 proof stamp. To the left of these stamps is a unit stamped into the leather "S.D.N. 935." This is a 'custom' stamp that would have been done by a soldier outside of the factory. The holster leather is strong and excellent with no major issues. The top leather has some surface wear, but no major flaws. The stitching is all original and in tact.
