Brass tsuba signed "Shigenori". According to Haynes Index he was from Shinagawa in Edo and died before 1781. This is really a strange set of information but this is all I could find. Saying that I have no way to verify na signature as I was not able to find verified examples.
This tsuba looks like it was inspired by the style of Tsuneshige. So the maker could be his student.
