I got a scratched up little teapot at the thrift store and can't find a mark or stamp on it anywhere. I think it's silver, since it's not magnetic and rings like a bell when struck.

It may be plated, there's some pitting and discoloration on the side (visible in the photo).
I need all the help I can get to ID it, or finding the mark if it's hidden.
I'll be looking through the care subforum to find how to get those scratches out, but I need to know more about it, first.
