Wasn't Frederik Fabritius Danish, although of Dutch origin? It is a sugar sifter, not many olives in ca 1800 Northern Europe. The top mark is the Danish three tower mark.
Eh, Dutch/Danish - so close (they do both start with 'D'). As AJ said, it's a sugar sifter, the pattern is now typically called 'Empire' - this piece is of the period. In that era, the three-tower mark would indicate Copenhagen, Fabritius the assay-master, the bottom mark looks to be a 'Taurus' symbol (or perhaps 'Aries'), so assayed in May (or April), 1803, at least .826 fineness - the 'FK' maker's mark has been attributed to Franciscus Kozlowsky, working 1798-1813. ~Cheryl
I don't mind being called Danish, I like the Danish. I don't know how the Danish feel about being called Dutch though, but I suppose there are worse things.
