Arisaka Type 30, Type 38, and Type 99 bayonet. Made by Toyoda Jidoshoki Seisakusho (Toyoda Automatic Loom Works), under Nagoya supervision. It has a straight contoured crossguard, with the serial number 3080928 on the pommel (these numbers are quite faded).
There are chip marks on the upper middle half of the blade's edge. There is rust all over the blade, crossguard and pommel, but no noticeable pitting. There is some chipping on the wood of the grip. The bayonet release latch still works.
This bayonet does not have a sheath.
