A maker's mark struck twice on an early 18th century spoon could be London or, I guess, any of the regional centres. Ebenezer Coker of London, who is a known spoon maker, entered a mark similar to these in 1738 but I would not want to claim this is definitively the same mark.
Thank You. I think I leaped to absurd conclusions (again, as usual) once I found the teaspoon from Cork, I assumed the rest were all English Provincial.
