Silver knife, called 'Zeeuws Paeremes'. It is marked with a really small mark, looks like M10 but here I cannot find a match. Help will be appreciated!
N10 see;
Fa. J.P. Niekerk, this particular mark registered in Schoonhoven 1901/1943. https://www.925-1000.com/forum/viewtopi ... 82#p194182
Schoonhoven made silver for the Zeeuwse market. The script-letter I used 1906-1953; Duty mark for unguaranteed standard of fineness new silver objects of national origin. This mark was used on all new Netherlands silver objects below legal standard of fineness, those with non-precious metal additions, and new heavily silver plated objects, as long as the average precious metal content after melting with the base metal was at least 250/1000. It was also struck on rejected objects which had been submitted at lowest legal standard of fineness. In that case the maker had to choose between destruction or unguaranteed marking. This mark was sometimes mistakenly used on old and foreign objects and in 1927 also used on objects of old national origin. Valid from 1906 till 1953.
