Good find.
Funny, I just picked up a Nagoya 38 Carbine too. It was missing some bolt parts but overall a good gun. I contacted a friend who is getting rid of his collection and told me in no uncertain terms he was no longer collecting or trading.....PERIOD! I told him I picked up a NO series Nagoya carbine with 3 digit serial number. His reply. "That's the only one I am missing for my carbine set.....bring it out to trade on.".......LOL
I own firearms not to fight against my government, but to ensure I will not have to.
