19thC Prisoner-Of-War Work Miniature Bone Dominoes

I love the history of these kind of items, made by the French prisoner-of-war in the early 1800's from scraps of cow bone to either while away the time gaming or to be sold for food money. This part set comes in a delicate light wood box with a sliding lid, they are a miniature size measuring just 15mm long x 8mm wide. The condition is excellent but a few are missing from the set, there are 22 in all one being duplicated.
