Flask Vintage Gentlemen Sterling Silver Glass and Leather

This is a gentleman's flask that has a sterling silver bayonet cap, collar and base. The top of the flask is covered in leather that has splits and scrapes. It has seen a lot of life, would hold about 6-8 ounces and is marked sterling silver on the base. It measures 5" tall and 3 1/2" side to side. One side of the base has a cartouche that we believe is a monogram. There is some tarnishing, but overall the silver is bright. has the makers mark of an eagle and name, Black Starr and Frist. It is futher marked with S216. There is a dent on the corner of the silver base, the flask cork is intact and the flask appears to be liquid tight. This flask could be used for it's purpose or simply a part of a collection.
