This is a post Civil War Pewter Glass Whiskey Flask with a 6 ¾” height glass body. The top wrapped in split cane and cord matrix to protect the wearer in case of breakage. The base with removable cup, 2 1/4" deep 3" wide with no splits and light wear. Pewter neck and screw off top with brass chain, possibility missing a cork washer. The cord appears vintage but unknown if the original. Over-all in very good condition with light age soiling and light signs of use.
