Q667. Kinko fuchi kashira. The inside dimensions of the fuchi are 1.7 x 3.4 x 1 cm. Tha nakago hitsu-ana is .8 x 2.7 cm.  Brass or copper plate with shakudo and gold bats and a silver crescent moon. I’m no authority but I’d be surprised if this isn’t Nara School work. The set comes in a box and is in excellent condition. $275.
