The lacquer on the scabbard is chipping away. I would say about 30% of the lacquer is gone. Mike Crenshaw looked at it for me at the gun and knife show today. He is the one who directed me to this site. I really appreciate all the info you’ve given me. I’ll try and find someone in Tennessee who can help me authenticate it. All I really know is that it was brought back after v-j day as a war souvenir by a friend of my uncles. He sold it and a namboo pistol to my uncle and I got the katana when he passed. Do you know when Nagasone Okihisa was making swords? I’m just trying to get a rough estimate of how old this sword might be.
