You guys continue to amaze me.
Steve, the pic you posted does look very like mine, indeed.
So, the shinchu zogan on mine has most probably (probably definitely) fallen out years ago.
One further question. I note that in both Steve's example and in mine, the fine brass inlay follows, to some extent, the outline of the kozuka ana.
So, if the kozuka ana is a later addition, does it follow that the fine brass inlay around it is also later?
I know its condition is poor, but I'm glad that my tsuba was at least interesting to you.
Thanks again to all.
I'll see if I can get one or two more shots at an angle and in natural light when possible.
