Hi, I have this wakizashi sword and need help telling who signed it. I found some late edo period tiger motif ones that are very similar with similar quality ray skin, gold tigers on the handle, gold enhance tiger related adornments, but this signature is different and this one is a horse motif. There is the tang mei signature, but there is also something written on one of the other parts. Any help with when it was thought to be made, who signed it, what the other signature is, if there is any record who it went to? Any neat history would be great. I have looked at hundreds of signatures and can't find a match. Also, the first character is boxed, is that symbolic of something? I saw no others with the first character placed in a square. Please let me know any detailed pics that could help.
