I have got a person saying that on another board. Can you provide any info on the smith, date, place of manufacture? Muromachi period is from 1337-1573. A fairly great expanse of time. Any way to narrow that down a bit. I can't seem to find a smith with this name from this period. Any help? I would love to finally put this to bed sort of speak. I have a word out to Christies in NY and the NY Nihonto club. As well a local expert willing to come to my home, who believes it Kamakura, who also told me many would think otherwise but since this is a different type of sword it might not fit normal conventions. I am paraphrasing. I really dont care what period its from I would just like a correct and accurate attribution. Feel me? I have no commercial interest in this, and will sit in my collection regardless. The previous owner had it since '47, I intend to keep it at least that long. Thanks for any help.
