Designed to be used with the Japanese Grandpa Nambu series of semi-automatic pistols, this wooden shoulder stock holster has a telescopic section. When attached to the butt of a Grandpa Nambu pistol, both the pistol and shoulder holster stock form a carbine. When not being used as a carbine the pistol can be stored inside the stock by a hinged door at the end. The shoulder stock holster is marked with the serial number "2220" on the holster loop bracket for the holster straps and the metal collar at the front. The holster straps are absent. This holster stock became quickly obsolete in favor of a leather holster.

Fine. The shoulder stock holster has scattered scratches and dings overall. A small crack is between the leather loop bracket and the hinged door. The telescopic section has cycling wear. Writer cannot recall ever offering one of these separate of a Grandpa Nambu!
