Tri Sectioned Glass Flasks, Tan and Brown Leather Wrap

This vintage glass flask set is comprised of 3 flasks with metal (sterling?) screw tops that fit into a brown and tan leather wrap. The set is 5.5" high to the top of the screw top and 11.5" in circumference. Each glass flask has a ground glass stopper that fits perfectly into the ground neck of the bottle (see picture 3); the tops, I think, are sterling (though not marked) and lined at the top with cork. Obviously an elegant, expensive item in its time for a gentleman. Condition: 1 flask has a chip in the bottom (but it is only in the heavy base, doesn't breach the container and doesn't impact utility; see picture 4); 1 of the stoppers has a rough spot on the bottom but all are in amazingly excellent condition; the sterling tops have some minor wear; and the leather has some wear but no tears. Overall, very good condition for a very old item. I don't know how old this is but would guess late 1800s or early 1900s if not older.
