Hello!
i am having difficulty dating this mark on a spoon as the shape of the lozenge is throwing me off. Is it 1798 Edinburgh? The maker is of course too worn to confirm but perhaps the date will help me find it.
Yes, I read this as 1798 too. I think the maker’s mark may be upside down - could it be ID for James Dempster? I have also seen a similar mark with the initials IP in an oval punch on a 1797 spoon, but have not identified it.
i do not see much Scottish silver and could find no example of the chamfered town lozenge (vs shields) and there is not much, at least that i could find, on-line regarding the Scottish assay marks.
The maker mark seems to be struck inverted with the first letter R. i will have to look at it again and will update.
Could be RG for Robert Gray, a Glasgow silversmith who was using the Edinburgh assay office at this period and one of whose marks was in an oval punch. But we’ll probably never be sure.
