Greetings, I was contacted by a local martial arts Black belt today and was shown this katana. He recieved it from his late judo instructor several years ago. At first it appeared abit fresh to me but there is a showa stamp present, I believe. I was granted only a short time period to examine and take pics and I apologize. These are the pics, any assistance greatly appreciated. This is not in military mounts. Best, Bill Bourque
