Antique Rare Handmade Japanese 10 Ceramic Beer Stein / Music Box

Antique/rare, handmade, Japanese 10 ceramic beer stein / music box. The bottom 2 of this mug is the music box portion that plays an unknown song (wind-up mechanism, song and stop/start pin all work perfectly). There is a mechanism/pin that stops the song playing when the mug is put down on a table and then plays when it is lifted off the table and held.
