No unfortunately I don't have a photo of the backside at the moment. It looks the same, but I can't say if it's identical without examining it first.
I'm not particularly worried about the tsuba I just want to learn more about it. (Paid 35,000 Yen / $250).
It's part of a birthday gift for my father, along with a Showa-to from the same dealer. And I don't want to lie and say the tsuba is Edo period, 200 years old, if it's not.
To be clear: the tsuba did not come with the sword, I choose it separately.
