T410.  Iron tsuba with gold and shakudo inlay.  7.7 x 8.1 x .6 cm.  The nakago hitsu-ana is .9 x 2.6 cm.  Somewhat unusual composition here: this tsuba is thick at the seppa dai and at the rim, and thinner between.  Also, it is very slightly mokko shaped.  Mountains in the mist and water below, I believe.  Looks like the prow of a boat peeking out from behind a rock at the bottom.  The hitsu-ana are nicely plugged with shakudo; condition and patina are excellent.  $175.
