This is a dead stock item. Tokai Gakki's Folk Harmonica Humming Bird I believe it's from the mid to late 1970s. The exterior is chrome-plated metal, and the body is made of wood. Keys are A and C. I was given two of them from a case found deep in the warehouse of a dealer in the Chubu region. Unused. - Model Name: Folk Harmonica Humming Bird - Materials: Metal, Wood - Country of Manufacture: Japan Thank you for viewing.
