Original 1864 Carbine Leather Sling with Swivel Snap
The base of the Swivel Snap is marked with 'U.S.' and inspector stamp 'T.J. Shepard'. Inside the snap hook itself is the stamp "O.B. North & Co. NEW HAVEN-CT", who had contracts to supply 29,000 swivels between May of 1864 and June of 1965. Leather is still supple, and the complete sling is fully functional.
