Hi Tony, Tsuba is in the Oeder book, page 90, nr. 758
try a quick translation:
Tsuba from iron, great.
High relief with different metals,
on one hand the Sennin Koshohei with his animals
and his brother Shoki under the tree
on the other hand Sennin Shonken riding on a sword over the waves
under a cherry tree, on the left a waterfall
Kita-gawa Zengoro, lives in the town Hikone, Omi province,
worked with Namban-tetsu
probably Soten I
