T185.  Iron sukashi tsuba with brass zogan.  7.9 x 8.4 x .45 cm.  The nakago hitsu-ana is .9 x 2.8 cm.  This tsuba comes in a box with Dr. Sato’s hako-gaki to Onin.  There has been some speculation that this tsuba is actually Heianjo Zogan, a group that came out of Onin.  The man who sold me the tsuba in box told me that they belong together, that this is the tsuba Dr. Sato wrote about.  It’s a wonderful tsuba in any case: excellent dense iron and finely done inlay.  Most of the inlay on the rim is missing and most on the faces is still here.  There is no center post in the box; not sure if there is supposed to be one.  $400.
