Bayonets:
Top - Jinsen arsenal.
Bottom - Manufacturer - unknown. No readily visible markings. I haven't pulled the grips off (if so then I don't remember) so perhaps there is something under there.
Jinsen arsenal close-ups. I got this one with the T99 I bought from Bain and Davis.
Unknown close-ups. Interesting carvings in the handle. This was from my dad's friend where he used to work.
I don't know if this is supposed to be a "46".
Although I have Japanese ancestry, I neither read nor write Japanese. No habla Nihongo (how's that for mixing it up). Okay, in your best Toshiro Mifune voice say: you are a disgrace to the
Japanese!!
