Adopted in 1921 as the standard Japanese Army signal pistol until the end of WWII. The left side of the frame has the Kokura Arsenal cannonball proof next to the model markings and serial number. Grooved grips with lanyard ring on butt. Comes with a brown leather holster. The inside of the flap is stamped with Kokura Arsenal markings.

Excellent with 95% original blue finish overall with the balance a smooth brown patina. The grips are also excellent with a few minor pressure dents. Mechanically excellent. The holster is very good with age cracking and some loose stitching.
