I have a bayonet that I believe is a Arisaka Type 30 Training Bayonet. I has one screw on both sides of grip with scabbard. There are no marking on the grip or near the blade wear i've seen other bayonets have marking on it. There is no edge on this blade so it has to be a training blade. It was my fathers and I found it behind his door in his living room when we was clean up his house after he passed away last year. So if I could get a little help to confirm this would be awesome. Thank you for the help.
