Vintage cruet set

Vintage cruet set…only has the salt and pepper bottles, think the missing two were for vinegar and oil. Extra holes could be used for spice bottles, I use mine for toothpicks. Cute on a rustic table, or to move salt and pepper around together. Not sure type of metal, no markings. Only damage is on top of pepper shaker some spots on the metal. Glass is good no chips or breaks.
