I just bought an Arisaka from my son and I don't know anything about Japanese rifles. I wonder how much collector's value there is. It's pretty dirty but all the parts are there and I think it will clean up well. The mum is ground off, so I suspect that lessens the value. Does anyone other than Norma make brass for it? At over a buck a casing, this is going to be an expensive proposition if I decide to keep, because I'll have to shoot it. I paid what he paid for it, $25.00.
