This is an original non-excavated socket bayonet for the Civil War
'
Springfield military .58 caliber rifle. This one has a full-length blade that has the "US" stamped at the base of the blade. The socket is also in nice shape and it has the original lockring and screw present. This pattern was designed to fit the U.S. military rifles of the 1855, 1861 and 1863 patterns by Springfield or the muskets made by the contract makers either one. It has a dark mottled color tone surface on the socket and blade. This one will look fine on many of the guns that are out there. This will be a solid addition to your gun or just for display by itself.
