Vintage silver duck head wine drinking horn

Vintage Russian folk art silver wine drinking horn with duck head mouth at the end. The silver is hand etched with a vine and leaf pattern at the wide end and is stamped in multiple locations. There is a stamp with ‘r, a hammer and sickle inside a five-pointed star, followed by 875’ which is the standard for Russian silver. Other stamps are hard to see. There is also a round sticker inside the rim of the horn but is illegible. The horn measures approximately 8” long with a 1 1/2” wide opening.
