I believe this is Russian silver although these tiny marks are notoriously hard to research properly. The research I have done in a limited way confirms what I have listed this perfume as. The marks are clearly photographed so if anyone with better knowledge feels otherwise PLEASE let me know so I can amend or change this listing! Measuring 2 3/8" by 1 1/8" this bottle is in perfect condition with no damage to the enamel. Age is unknown but my feeling is that it's from around the 1920's.
