Very good condition WWII Polish Kbk.S.wz.31 Mauser .22 single shot training rifle that has Radom Arsenal and Polish eagle markings on the receiver ring and dated 1939. Receiver side rail has the model designation. Rifle is NOT import marked and has all matching serial numbers. Metal finish is nice original black showing a little normal wear. Bore is bright and excellent with strong rifling. Stock has original finish and shows some normal handling marks along with a duffel repair. Underside of buttstock has a matching serial number. Complete with correct original Polish leather sling which itself is scarce. A hard to find WWII Polish Mauser .22 training rifle that will make a fine addition to a collection.
