Netherlands. There is very little, if anything at all, known of Dutch chess set makers in the 18th century. The sets below are examples of the so called "Dutch" chess set, made from the 18th till early 19th century. It is believed that they were made in the Netherlands (or Flemings), but there is no actual proof. The last set from this series could very well be from Erbach in Germany, made early 19th century. Similar design, but with figural Kings en Queens, is known as well.
The 2 sets at right are a recent (September 2024) acquisition. Both sets have their original box and there is a periodical chess board with one side with 64 fields and the other with 100 fields. Such boards are known as Dutch as well.
The 1st set is very interesting because it has pieces for chess and disks for International draughts. There are 2x21 checkers, so there is 1 spare on each side. The lockable box and the board were always together in the family. Set, box and board are in pristine condition. White bishop's top maybe replaced.
The 2nd set and box, unfortunately, are rather damaged. Next to some chips, are black King, white Queen and 4 pawns broken. Most bits of pieces are present, except for a pawn finial and some minor chips. See picture of all damaged pieces. But it is a nice set in a less common bone and wood combination. Not sure it is ebony. The finials on the rooks are unusual too.
