This fantastic flask is as smooth as a pebble from the French Riviera. The sterling silver bayonet cap is engraved "JJ" with the date 1892 and letters, AWS. It is clearly hallmarked, "Gorham Co. 0145" on the neck. There is a small dent on the cap, and that prompts the imagination. It measures 6 3/8" long and 4" wide at its widest point. It would make a wonderful gift for the collector or to add to your own unique collection. What a piece of history
