T489.  Kinko tsuba with summer grasses.  5.7 x 6.3 x .35 cm.  The nakago hitsu-ana is .8 x 2.7 cm.  This comes with a paper from the NTHK-NPO (Mr. Miyano’s group) dated 2016 and giving the tsuba to Ichinomiya Tsunefusa.  I’m not sure what the plate is here, possibly shibuichi or patinated yamagane (copper).  There are shakudo, gold, and maybe some silver inlay.  Condition is excellent.  $325.
