The spoon has the following hallmarks from left to right.
A maker's mark as shown in the sketch below, an anchor, a lion, the head of King George, and the capital letter T.
From this I deduce that it is a Birmingham assay mark, sterling silver, made in 1791.
Since I have made several unsuccessful attempts to photograph the hallmarks I have drawn the maker's mark as best as I can using an 8x magnifying glass.
Can anyone please suggest who the maker might be?
Any assistance most appreciated.
