that is a 22 caliber made by harrison-richardson gun company-Gardner,Ma.-the firing pin hits the rim of the bullett,rather than the center.
With the exception of guns like the Thompson/Center, a single shot weapon that changes barrels, there are few .22 pistols that can EASILY converted to a larger caliber. The .22 is a rimfire, and firing pin is in the wrong place for a centerfire cartridge.
Numrich Arms probably has them, but this is an item any gunsmith should be able to manufacture.
No
All firearms that are in caliber .22 Long Rifle (LR) or 22 Long or 22 Short are rimfires. If you look at the face of the bolt, you can see the firing pin. If it is in the very center of the bolt face, it is center fire. If at the edge of the face, it is rimfire.
