I just inherited two swords from my grandfather. He was a Marine in the Pacific in WWII and stationed in Nagasaki for six months during the post-war occupation. He brought back a Nambu Type 14 pistol and two swords. One sword is a NCO type 95, although it's black, (possibly painted?). The other sword is a wakizashi, (20.5"). It has a gunto tsuba and katana length saya. I'm unsure of the age of the koshirae. In the 90's, my grandfather wrote a letter to a fellow marine in Japan who translated the mei as "Hizen Kuni Yoshinaga". This appears to be the case, but I'd like confirmation, especially for the last character, since it doesn't look exactly like "naga". I've done a lot of research already. "Hizen Kuni Yoshi" looks perfect, so that should narrow it down. Some internet research points to YOS595. I consulted a 60's edition of Hawley's and came across a Meiji era Hizen smith named Yoshinaga. Hawley listed that smith as "YO 410" and the notes said "Same as GO 4". GO 4 is Gozaemon. The Nihonto Club website has contradictory information and lists the Kan-ei era Yoshinaga with a first name of Gozaemon. I'm not sure if that's bad information or if Hawley had later corrections than the 60's version I consulted. I've asked a Japanese friend for help in translating. He said the last character could be a shorthand version of naga, but it's not one he's familiar with. Thanks in advance for any help.
