I've run across several sugar bowls with spoon holders, most often in Victorian American silverplate, have also seen a couple of spooners with additional holders around the rim. Agree with Doos that this appears to be a sugar vase, but does seem rather large. The spoons do seem to be replacements, but the bowls have a typical French extended point tip, where are the marks on the spoons located? Could the "2" be the Dutch 833/1000 mark Tardy shows as being from 1807-10, during the French occupation? (Definitely wandering way out my area of knowledge now.)
Lovely and unusual piece!
