Silver & Crystal Ice Bucket

I have a gorgeous silver and crystal ice bucket but cannot find anything out about it. I’ve learned a little about hallmarks over the last couple of years, but these ones have me stumped - I can’t identify any of them. If anyone can help, I would really be grateful. Thank you. Caroline.

JD&S is James DIxon & Sons of Sheffield. The rubbed symbol on the left is EP, for electroplate, so I regret to tell you that your ice bucket is electroplated rather than silver.
