T303.  An unusual tsuba worked in brass.  6.3 x 7 x .4 cm.  The nakago hitsu-ana is .7 x 2.4 cm.  Unusual for a variety of reasons.  1st, brass isn’t that commonly used in tsuba and when it is I expect to see bright brass, not the patinated plate we have here.  The irregular shape (cloud) is not often seen also.  I think this is late Edo work but it has been mounted to a sword in the past.  The carved dragon is very well done, moving in and out of the cloud and with copper whatever those things are flowing from its side.  I think this to be a fine piece.  $300.
