The following details might be insufficient to draw a response but are the best I can offer;
Posted on the NMB on March 28, 2014 by Grey Doffin was a tsuba with coplicated brass wire inlay design, all in good order.
Grey stated it to be an Onin (or Heianjo - zogan) tsuba. Another with similar inlay appears in Gary Murtha's book on Onin-Heianjo-Yoshiro book on page 85.
I just don't know how to get those depictions onto this post so if not good enough we can forget the matter, but if anyone can deal with this as presented I would be interested in purchasing an example of this type of work.
