I like that story, provenance with the rifle would make it a prize piece for a guy like me who collects oddball stuff. One of my favorite pieces is a Jap Type 30 bayonet stuffed into a dried out British scabbard with half rotted British frog. I picked it up in England so my guess is that a Brit lost or broke his bayonet and snagged the Jap. Could have been the other way round and a Brit took it home at the end of the war, or it could just be some goober stuck the two together because they fit and he didn't know better or didn't care. It has that look though, like it has been that way for 70years and has correct wear to show it has been a set for a long time. I also have a Chinese Mauser which was converted into a Jap trainer and has the original (I think) sling. Odd is cool, I've seen a few SS contract rifles ( legitimate ones ) and they bore me. My Type 38 with the buttstock cartouche that reads "Japanese type teeth" or "Big teeth"......I love that gun.
I own firearms not to fight against my government, but to ensure I will not have to.
