The Type 26 was an Imperial Japanese Revolver, first adopted in 1893 and used until the end of the Second World War. It was chambered in 9x22mmR Japanese Revolver, which was a proprietary cartridge similar to the .38 S&W. It is a top break revolver based on a Smith & Wesson design; notably, it has a bobbed hammer, and is thus a double-action-only revolver.
Will consider trading for other pistol, revolver or long gun.
