C233.  Iron sukashi tsuba signed Yamakichibei.  7.3 x 7.7 x .3 cm.  The nakago hitsu-ana is .8 x 2.8 cm.  The consignor of this tsuba tells me it is 3rd Yamakichibei; works for me.  The sukashi is cloves and the finish is yakite (almost melted).  Prominent tekkotsu on the rim and condition is excellent.  $400.
