T418.  Iron sukashi tsuba.  8 x 8.2 x .5 cm.  The nakago hitsu-ana is .7 x 2.7 cm.  This is quite distinctive work, with ample brass and one instance of copper inlay on each side.  I’m sure this could be tied to a school of tsuba making; I have no idea which school though.  Condition is excellent.  I can find only one tiny piece of brass missing from one of the flowers; all else is still here.  $300.
