Help with signature on Tsuba

[Kmad]

Hi All, any chance you can make out signature on this tsuba I just got? Much appreciated , ken

Ken,

the first MEI character is perhaps MUNE, but the rest is difficult to read. Maybe it would be easier to identify if we had good photos of the whole TSUBA.

Off to a new years party but will put up better pics tomorrow, thanks ken

宗兵衛

(?)

Sōbei

(I have found two who signed with this name, one in Asakusa, Edo, and the other in Satsuma.)

Looks like 宗與 with the last character as a Kao.
