pocket sized Thorens music box

I have a small, pocket sized, brass music box. It has the name Thorens Switzerland on the inside mecanisims ans also on the wind piece in the back, it is in excelent working condition, it is missing a tiny screw for the inside, but does not effect the performance of the wheel. On the outside of the box it says "hot strawberry" inspired by Cutex. It has a loop on the top of the casing witch would be for some form of chain.
