Today I decided to Authenticate the very first thing I ever bought in my WW2 collection last year. back then I was only 15 and knew nothing about collecting, all I knew was it was cool, and it looked old. i bought it for 40$. i believe this is an Arisaka type 30 training bayonet. I'm hoping that its authentic, but you know how it goes. Any extra information would be very much appreciated. As always, thank you for looking!
PS. the mark on the handle is a 30 not a 50
