K61.  Kinko tsuba with geese.  7.2 x 7.6 x .33 cm.  The nakago hitsu-ana is .8 x 2.8 cm.  This tsuba may be shakudo but I think patinated copper is a safer call.  The geese are shakudo with gold and silver; the reeds are shakudo and silver.  There are a few fine scratches on the surface (more visible in my pictures than in hand); otherwise condition is excellent.  $300.
