I don't know what model that is, but I have seen one like it that belonged to a neighbor of my family when I was a kid. Mr. Howard was a older man who ran a trap line and had an old, worn, cut-down Stevens single shot bolt gun in .22 WRF that he carried in his pack basket to kill fishers, foxes, and 'cats. He was the reason that I shot .22 WRF ammo in my Savage 24 and 65 when I was hunting something that I wanted to eat and saved the .22 WMR ammo for varmints..
