Just unearthed from family storage. Father was in 158th regimental combat team, New Guinea, Numefoor Island, Philippines, Japan. Bayonet had National Denki under Kokura supervision markings, serial number with either 2 or 3 characters followed by 32857. Only thing of possible interest is leather scabbard, with leather covering a wooden holder instead of metal. Also has two leather loops to hold on a belt. Any assistance and/or comments always appreciated.
