Thanks. I will post a picture of the whole thing soon. At least we have established (I think) that there is nothing distinctive enough to confirm a maker or a date.
Just looking at an unremarkable piece of plated silver. The mark underneath includes EPC so presumably that is what it is. Very little other information as far as I can see but I would be interested if anyone could identify the maker. http://wiki.diyfaq.org.uk/images/b/b2/Hallmark_EPC.png
