Help with Silver Clam mark

Greetings, new to this site and VERY unfamilar with the silver hobby.

This is an electroplate mark (so not silver) of Padley, Parkin & Staniforth of Sheffield. This site gives their dates as 1846 - 1875.


Great! You’re very kind. At least I know I’m not giving away something really valuable. Have a good day. - Jamie
