T221.  Iron sukashi tsuba signed Tadatsugu.  6.6 x 6.6 x .3 cm.  The nakago hitsu-ana is .8 x 2.6 cm.  The collector who owned this tsuba before me gave it to Umedata Tadatsugu; I’ll take his word for it.  Condition is excellent (no corrosion of the fine sukashi elements) and there are the finest of tekkotsu on the rim.  $275.
