Hi guys,   I bought this tsuba recently with a lower offer . It came with a dealers NTKK ( not from NBTHK ) which I have not had before. On the listing, it showed maker was named Shushi Saku ?.   I think it maybe Kaneharu saku. Can anyone help with maker's name please, is the latter correct ? I have tried Kanji pages and others with a small amount of luck only.   2 pics are included and my other reference tsuba from Toledo museum made by Kaneharu late edo.   Many Thanks,   Mark.
