Is this Scandinavian?

[keswick]

Hi
I'm really not sure what this silver mark is!
I was wondering if anyone could tell me if it is or isn't Scandinavian, and who actually made the piece?

Any help is much appreciated

Kind regards

Forget the Scandinavian or Nordic countries, it has nothing to do with them. Your ring can maybe, MAYBE, be from USA.
