Q638.  Fuchi/kashira in yamagane (copper) with gold and shakudo inlay. The inside dimensions of the fuchi are 1.75 x 3.3 x 1.1 cm. The nakago hitsu-ana is .9 x 3.1 cm. Even though I see no birds, I think this is pretty obviously Nara School work. This comes with a box. Condition is excellent.  $150.
