T424.  Iron tsuba with conch sukashi and shakudo shells.  7.2 x 7.6 x .4 cm.  The nakago hitsu-ana is.8 x 2.7 cm.  This tsuba is signed but I haven’t taken the time to translate; sorry.  I believe when new this had a gold mimi; only a bit of the gold remains.  Great condition and the tsuchime (hammered surface) is a nice compliment to the sukashi.  $150.
