Here is an example of an early state marked US 1798 Contract Socket Bayonet. As is typical of most of these bayonets, delivered in conjunction with the US 1798 contract muskets. As is typical of 1798 socket bayonets from the middle of the first decade of the 19th century through the end of their production, the socket included a rudimentary bridge. The bayonet is cut for a top stud. The bayonet measures approximately 18 inches long overall with a 14 inch blade and a 3-1/4th inch socket. A thin top flute is 7 inches long. The metal has a dark attic patina overall with scattered fine pitting. It is clearly stamped on flat of the blade is "NC.US”. There is also an "H” stamped at the end of the T-mortise on the socket. This would be a fine addition to any display of US 1798 Contract Muskets or War of 1812 era weapons.
