My father served in the OSS in WWII. His team was the first Allied soldiers to enter Peking in 1945. Really long and interesting story, but he ended up with a Japanese 'samurai' sword, allegedly from a Japanese General. My brother, years ago, copied the inscription on the tang of the sword, sent it to someone in Japan where it was id'd as a 16th C sword. I would like to get it professionally appraised, but have no idea where to look. Brother lost all his documents! Anyone know where I can start?
