vintage victorian style metal music box with wind up humming bird

vintage victorian style metal music box with wind up humming bird. Has markings on lid wit a letter c inside of a circle and the words FSG 2003 Very unique and heavy (solid) plays an unknown musical tune. Humming bird looks to be set in a bird bath ? Humming bird does not move but music plays , I’ve never really played with the music box, it was for a display purpose only ..looks to be possibly brass metal features as it is heavy.. last one seen was sold at 995.00 this is the second music box like this that I have seen.
