Thanks Richard, ill try some searching with Myochin and Shoami now.
It is a very chunky Tsuba for sure!
I am pretty confident the nunome was only in the places as shown in the pics, obviously some has come away, unfortunately my camera work is light years from your own, but had they have been better quality, you can still the extent of the hatched filed marks to where they used to be.
So front of Tsuba had three areas of nunome on the mimi, the back had two areas. One of the webs on the front never had nunome and two webs on the back also never had it.
I guess another reason for it probably not being Kinai is I have read almost all were signed.... this obviously is not signed.
Thank you, two more potential schools to reasearch is great!
