Looks you are on to something there David. I've never owned an Arisaka but have handled a few briefly in gun shops. Sorry op for my previous comment. I just didn't recognize one that naked I guess.Arisaka looks pretty good. Heavily modified if it is, some other type of Mauser action if it isn't. Nothing about it looks belt-fed to me.
