Vintage Floral Rose Ballerina Jewelry Box

Very cute, classic vintage 60s jewelry box. The wind mechanism doesn't appear to be working...so she doesn't spin, and there is no music. It sounds like it could be fixed, but I haven't opened it to see how to fix it. Box is in good shape. A few knicks, scratches, stains due to use/age. There is also a water stain along the back - see Pictures. Slide lock closure. Red interior is clean. Lots of room for jewelry. See pictures for measurements Made in Japan
