We bought a covered butter dish (with glass insert) at an estate sale. There is a hallmark on the bottom - no other marks anywhere else that I can see.
Both the cover and the bottom a shiny and bright.
I can’t make out the first two characters, though I think the 2nd one could be an “R”. They are followed by an “S” and then a small crown. I have attached 2 pictures.
I’m curious about who made it and if it is silver or silver plate. Any assistance will be greatly appreciated.
