Sterling Silver Enamel Mechanical Charm - Carousel Merry Go Round with Leopards

Maker: Unknown Item: Dating to the 1960s or so, may I offer this mechanical Sterling Silver (hallmarked as pictured) charm - a carousel merry go round filled with what looks like cats - leopards and panthers. Size/Weight: 9/16" high x 1/2" wide. Weight is 2.3 grams. Condition is very nice though, as you can see by my pics, there is wear to the enamel. This can be remedied with either colored Sharpie pens or cold enamel paint. Yes, the piece moves round and round and it is a far cry from the ones I usually find that have horses.
