Hi John,
Congratulations on a nice sugar sifter spoon, which seems to have been made (or retailed) by Johannes Schiotling (1762 - 1799) , Amsterdam in 1785.
ISL ie Johannes Schiotling
The second oval mark is hard to interpret (fineness, standard mark?)
Amsterdam town mark and date letter capital A (I may be wrong, I have been counting but I say 1785, but you see it stands to be corrected).
The other marks are secondary as you mentioned. The crowned "O" is a tax mark and was struck in 1807 on old items re-assayed.
I presume that the crowned ligated "TE" or "ET" is a French import mark used from 1819.
The "V" mark has been used in The Netherlands to mark items of unknown or foreign origin. This one seems to be before 1906.
He was as you can see a native Swede (perhaps his name was Schiötling) ending up in the Netherlands. As a Swede myself I see a strong resemblance with the in Sweden wellknown and beloved pattern "Gammalfransk" or in an ad from a major French silver cutlerer in 1891 named "Palmes Suédois", despite its French origin.
The Rijksmuseum in Amsterdam writes this about him.
Johannes Schiotling (1730-1799)
Johannes Schiotling was born in Gothenburg, Sweden. In 1747 he started a six-year apprenticeship to Olof Fernlöf, one of the best silversmiths in Gothenburg. In 1753 he passed his journeyman exams. Nothing is known about the next nine years; probably he travelled around until ending up in Amsterdam in 1762. Schiotling registered as a master with the Amsterdam silversmiths guild and married. In Amsterdam a group of silversmiths gravitated around him. His firm's produced numerous pieces and Schiotling focused increasingly on retailing rather than making silver objects. Although his workshop produced many candelabras, he sold many different objects. And indeed different styles: from Rococo to Neoclassical.
