Information about this scabbard

These large straight scabbards are all made with a heavy black lacquered leather body and sheet brass mounts.  The round brass ball finial tip is unique to this type.   

Although these scabbards are straight, their wide body width handles the curved blades for which they were made.  

 The throat is open to the edges of the mount and the leather body is exposed.  It is the 26 mm wide frog loop in the center of  the right side of the throat mount that makes this variation unique.  This loop is made of brass rod, bent into a U shape and brazed to the top mount. The mounts are attached to the leather with two small rivets on both sides of the throat and tip.

The throat mount is 83 mm long and 44 mm wide.  The tip mount is 119 mm long and 40 mm wide.  The overall length is approximately 600 mm long.

Albert N. Hardin, The American Bayonet 1776 – 1964, "There are two basic scabbards issued with these arms, differing only only in their frog retaining devices.  Due to the nature of the frog design, the scabbard with the flat rectangular attachment is considered the earliest scabbard, and those equipped with the more common, round button attachment are regarded as later models."
