Very nice solid vintage shape, and appears to be in good working order. It winds and plays when you slide the button below the key hole to the right, and plays through until you slide it back. It sounds great, and plays The Magic Flute, Eine Kleine NachtMusik, and The Turkish March. Sometimes the nut that holds the bar that slides to hit the mechanism comes a little loose and needs tightened. Aside from that I've found no issues with it.
Lock works, but can be finicky at times. Physically it shows normal display wear in the form of some light scuffing on the wood. Measures 11x7x4 with the lid closed.
