This sgian dubh has silver sheath fittings, and I can see a J.R.&S mark, along with what appear to be crude Edinburgh marks. Because I am new to the subject, I'm not sure how to interpret the other marks, or a lack of marks. I did see the silvercollection.it listing for JR&S on spoons by James Rettie & Son, Edinburgh, but the mark is not identical. Their other listing, of J.R&S is "not identified", and the mark is also not quite the same.
I appreciate any thoughts. Confirm it's an Edinburgh assay? Thoughts on whether this is Rettie, or someone else? I don't see anything I'd call a date mark, but is there any other information as to when it was made or stamped?
