Hi Ford,
Great to hear from you. Can't believe that Kyle is 19 though Miriam is a Mum herself now. Anyway, back to tsuba... Thanks for your wisdom, if it is a Bakumatsu piece that would account for me not having come across it's like all these years and would also fit well with the rest of the koshirae which would seem to date from the blade's production date; 1864 according to the papers. You might even remember the sword, strong koshzsori and o kissaki with a waisted tsuka.
Yes, I still look longingly at the Tomotsune tsuba from time to time, fancy you remembering that.
Always thrilled to see your work, you remind me of a poem which I will try to track down for you.
All the best.
