This piece is 18 3/4″ overall, 14″ blade, 3.9″ socket with 1.82″ stud to muzzle measurement and inside diameter of 23.7mm or 7/8″. Blade is marked with "C" with the remnants of a crown over 5 (see fig. 133, page 100 of the above). The socket shows a split at the seam and a tear leading to the slot. The metal surfaces show stains, light scattered pitting and old patina. This piece shows an engraved no. "18" on the top of the socket.
