This is an excellent example of a WWI 1896 Mauser semi-automatic pistol chambered in 9mm Luger. It is a standard WWI 1896 small ring variation with the late style "NS" marked hammer. Standard sights with the tangent rear sight marked 50-500 meters with the standard 23 groove grips branded with the large "9" on each side filled with red paint. Standard receiver and frame markings of "WAFFENFABRIK MAUSER/OBERNDORF A NECKAR." and "WAFFENFABRIK/MAUSER/OBERNDORF A/N." The Mauser "crown/U" proof mark is located on the upper left side of the receiver below the serial number and on the top left side of the bolt.
