Sorry to be such a novice. But do these marks look like silver or is it plated??? Looks like W R & Co S and a crown maybe???
WILLIAM RAE & CO Liverpool, but I have big doubts…
It’s certainly electroplated and the S probably stands for Sheffield so I also have doubts about it being a Liverpool company. This particular mark doesn’t seem to have been documented in our usual go-to site for electroplate but that’s not necessarily surprising as there is no requirement for any sort of registration of such marks and there are still many unidentified ones.
