Greetings to all. The in-laws brought back four deep soup spoons from the UK 17 years ago. He has passed and she has Alzheimer's and can't remember the spoons back story. I'm trying to learn more about the spoons as they're too deep to put in your mouth but better to sip from the edges. I see they're silver, made in Sheffield but I can't quite identify the years nor the makers. Any help is most appreciated!
