The maker’s mark definitely points to Langlands the Junior. However, that city mark of a beehive of rooks seems to have a flattened top and angular cut corners. Is this a common irregularity during his working years? The kloistered kitty seems to have rounded left corners and cut right corners here. Dutiful George looks a bit crushed by the weight of the world on his shoulders, and perhaps suffering a slight crack-up driving towards his occipital bun, but is otherwise well rounded and healthy enough to remain enthroned. [No date code letter of course, as would be expected for puny pieces of this period.] Looking at the drop, there is a pronounced round bulge at the end, which may only leave a faint trace on other samples, but is clearly circular and dome like on the teaspoon..is that a defining factor on authentic Langlands spoons? Anything that might narrow the dating range here?
There are some minor variations in the town marks during the period of Langlands's working life (1793 to 1804). Here are a set of marks from 1794 to 1804 where I am sure you will see a 3 castles mark similar to the one on your spoon:
