Spoon with worn hallmarks

[Granmaa]

Here is a teaspoon whose hallmarks are quite worn, so you may have to go by design. I'm not familiar with foreign spoons, but I'll tell you the differences between this and English spoons. This has the monogram on the back of the spoon and upside down. It is bottom marked yet only c.1820 (by my guess). The drop has a thumb nail indent.
