Kokura Arsenal Type 26 9mm Jap caliber revolver. Lower number #2381. Good plus to very good bore. Action works perfectly. Grips are very good. Cylinder has unfinished look with mill and machine marks. Left size of the barrel near muzzle has some pits which correspond to an area of the cylinder with pits. Probably laid on something long ago. This gun seems to have been finished in the white although it has some staining or patina now, but really shows no evidence of having been blued. Very interesting revolver.
