These marks bear a strong resemblance to John Glenny of Montrose, Scotland circa 1810-1830.
I am looking at a CD of photographs ' A Directory of Scottish Provincial Silversmiths and Their Marks' by Richard W.Turner, who is a contributor to this forum.
I am not an expert but if I owned the spoons that would be my attribution.
The mark is also recorded at the Edinburgh Assay Office
