Long story short. Grandpa picked it up in the war and passed it down to me. Recently had it restored and I'm trying to find a more definitive answer as to it's smith and history. Please see attached and I can take more pictures if needed. I intend to hold on to this until it can be passed down as well so I have no intention to sell. I'm just here out of pure curiosity. One attached image are some mei comparisons the polisher showed me during his research but we never came to a conclusive answer.
