Short version: What, if any, parts might one safely cannibalize, from an Arisaka (specifically Type 38) training rifle?
Long version: A while back (and with some helpful guidance from some members of this board), I pieced together a Type 38, from a barreled receiver. I know, the collector's value is gone, but I have a mum-intact, WWII, Japanese battle rifle; I'm happy with it (and I spent next to nothing on the project). However, I now have a mum-ground, barreled receiver sitting in my closet. Seems a shame to me, that it should languish in disuse. I have a number of ideas swirling in my head, but first I need to get it functional. I see dirt-cheap training rifles from time to time, and have been wondering if they might be of any use to me.
