Hello! I was hoping that I could have some help with a Christmas present I received. My in-laws appreciate my collecting of WW2 items and always try to find something unique for the holidays. This year one of my gifts is a Japanese Type 30 bayonet.
I'm not at all familiar with Japanese items but have started to do some research and this one appears to be correct for the WW2 era.
The only marking I could find on the blade was an arsenal mark on the right ricasso that indicates that it was produced at the Kokura Arsenal.
The pommel has a serial number of 70612. To the left of the serial number is is a kana within a circle, but I do not know what that means. There also appears to be a stamping of a bird below the serial number.
Does the hooked quillon indicate the period of production - earlier?
Any help would be greatly appreciated!
