12" long tapered flat faced blade, 1" wide at ricasso. Overall length 14.25". 1.5" socket cut for a bottom stud with a crude three-step "Z" shaped mortise and a very short .6" muzzle to stud distance. Muzzle diameter measures nominally .86", rear of socket diameter is nominally the same. As set screw hole is drilled through the base of the shank and socket to allow a wing nut to be used to secure the bayonet to the gun. No set screw is present. Crudely hammered neck is nominally 1.7" in length, roughly oval in cross section and of irregular diameter, measuring about .45" at the thickest point. Socket to neck junction is with a "shield shank" or "flanged shank" type joint. Socket with visible seam on the bottom of the interior and blade with obvious forging flaws. A similar example is published in Neumann's Battle Weapons of the American Revolution as figure 56.BB credited to the Erik Goldstein Collection and Reilly shows similar examples as B5, B10 and B33 in his reference American Socket Bayonets. The bayonet is accompanied by an old leather scabbard with attached leather belt frog. The scabbard fits the blade very well and may be original to the bayonet, although the frog is somewhat cruder and the brass button is somewhat incongruous.
