I have a sterling silver condiment set in its original box. The makers mark is J&RG which I think is Joseph and Richard Griffin. Unfortunately I can’t get a decent photo of the hallmark but it looks more like a Chester hallmark than Birmingham. The year letter on 3 of the items is an italic N which looks like 1913. The two bowls and original spoon have a totally different symbol for the date which could possibly be an O but is not exactly the one listed… Would these makers be in Chester at that time and why would part of the set appear to have a different date on them?
PS I managed a photo of the hallmark on one of the bowls!
