Hi Ringo,
Sugar casting spoon; the bowl with pierced work(Durchbruchsarbeit), to cast /sprinkle sugar over pancakes/small fluffy pancakes (poffertjes)/bread or other food items.
From left to right; the maker’s mark is
GG for: Gerit Regtdoorzee Greup, registered in the city of Schoonhoven from 1864/1915( used 4 different maker's marks), Lion Passant above 2, standard mark for large and medium work, 833/1000 fineness used 1814-1953, The Minerva head or Assay office mark with the regional assay office letter M for the city of Schoonhoven, followed by the date letter C for 1912. Unti 1931 the assayers were personally liable for mistakes in the result of their work. Until 1931 date letters were considered to be their responsibility marks. When in the course of a year the assayer of a certain office was succeeded by another one, as a consequence the date letters of that office were provided with a distinguishing mark. Usually it was a dot, but commas, crosses and stars also occurred. There are a few date letters bearing two dots; the result of two changes of assayer within a single year.
