Even in France; assuming it's France and not Belgium or anywhere else the franc was used and, a control number strongly discounts a personal set since so little Ivory was used to be a stock denominated inventory.

I bet it was made in Dieppe, too, since they were famous for carving Ivory and something none of the Paris shops did much of in the way of chips.

If it didn't have the "F" I would have guessed the UK...
