Beautiful vintage repousse saving silver plate snuff box collectable

Beaufully decorated in repousse, this snuff box has had me spending forever researching it. I can however only be vague ! I believe its c. 1800s. Its silver ( plated) with possibly some guilding coming through the top. Rocco style.

It has Cc stamped inside which may saving ( or may not be something to do with casting ???
There is a stamp on the back.

Overall in great condition with just the normal age wear on the edges.
Shuts firmly
