I picked up these two swans at a thrift shop. They measure about 5″ high and 4″ long. The only mark on the bottom reads “SILVER.” They are silver and enamel.

The wings come off one and each has a removable back as a lid for the interior, which is blue enamel. I can take more pictures.

I have no idea where they came from, what they’re for, or what they’re worth. Any help is appreciated.
