I am trying to identify exactly what a particular rifle is for a client of mine. He has a German Mauser. It is of the "long-stock" variety with the forend extending the whole length of the barrel. The gun appears to be unaltered. It has a "pear" or "tear" shaped bolt. The serial numbers on the barrel, receiver and bolt match. The receiver has the marking "WAFFENFABRIK MAUSER-OBENDORF A/N. It is marked both 7.6 S and U.S. 1906. It has both Crown U and Crown B markings as well. The hinge plate on the bottom is stamped "Germany." The gun is is great shape. You can tell it is old but has very little wear and likely has not been fired much at all. My research thus far indicates that it is likely a Mauser rifle imported into the U.S. in the mid-1920s and that it possibly could be a rare "Special Range Rifle."
