I can add the Dutch sword mark; small standard mark with numeral fineness first introduced with the 1953 marks renewal.
The maker's mark, to me it appears to be
VKB under a
crown above
crescent moon for; Koninklijke (Royal) Nederlandse Fabrieken van Kempen en Begeer N.V. or Koninklijke van Kempen en Begeer, date entry 1961-present, cities of Zeist & Voorschoten, Leiden en Zoetermeer. To make sure we have identified the right maker we need a clear enhanced image made with a good digital camera active macro/tulip function mode. Below the maker's mark for
van Kempen en Begeer for comparison.
