We need more information- make, caliber, condition, and all markings. The .22 Special was a rimfire cartridge. Please get us some more information, and we'll do our best-
POSSIBLY a rimfire revolver known as the Swiss Mini Gun. It is caliber 2.34mm, or about .092 caliber. It is not available in the US to due laws regarding import of firearms.
No such caliber as .32 Special. Use the caliber of ammo marked on the gun.
44 S&W Special is the caliber, not necessarily the make. If it IS a S&W, the Standard Catalogue of Smith & Wesson will have some information for you. So will S&W Customer Service.
