Produced by Kayaba Kogyo for the Japanese Navy up to 1945. Finished in a black lacquer overall, the three barrels are each marked with a rectangular stripe to indicate the type of flare to be loaded; yellow bordered by red on the left, solid white on top and black with green borders on the right. On top of the breech is the Kayaba symbol, Navy blossom marking, inspection proof and a naval anchor. The Kayaba mark is repeated on the right side of the frame and on the rear mounted cocking knob. Standard patent markings, with red and white filled safety markings, checkered grips and a lanyard ring on the butt. A brown leather flap holster is included with the lot.

Fine as assembled (mixed numbers on the barrel group and extractor), with 80% of the arsenal style black enamel finish, showing areas of brown patina, edge wear, scratches and spotting. The grips are very good, with some light scuffs. The holster is very good, with some cracking and scuffs. Mechanically fine.
