I have bought a really interesting silver spoon at a Copenhagen antiques dealer and I am looking for the identification of its maker and the date of its manufacture. The item bears a series of pricked initials with a single maker's mark, an engraving with a very basic Rococo design on the bottom, and the item further has a very interesting overall shape with a beak on the side reminiscent of those spoons that are used to serve sauces for meals.
From the style of engraving I assume it was made during the Rococo period (mid- to late 18th century) though the maker's mark is entirely unknown and I didn't find anything similar. From what I can see, it says "JF". Can please somebody help me identify this spoon? Thank you.
