Information about this scabbard

This scabbard was made with a black lacquered leather body and sheet brass mounts.  The throat mount is held to the leather with two small copper colored rivets widely spaced on each side, close to the leather edge.  The tip mount has a single copper colored rivet in the center on both sides close to the leather edge.  The leather body appears to have been contoured to the shape of the curved blade.  The leather side of the throat mount has a straight edge that is perpendicular to the leather body.  The leather edge of the tip mount is lightly curved outward toward the leather body.  The overall length is approximately 574 millimeters long.   

There are two sets of parallel lines impressed into the front side of the leather body that runs from mount to mount.

There is a small domed, 15 millimeters wide, brass frog stud brazed to the lower right side of the throat mount.  A brass plate with a blade shaped opening appears to have been brazed to the throat mount.  The throat mount is 64 millimeters long and 44 millimeters wide.  

Below, the separation on the bottom edge of the brass top mount show where the sheet brass was seamed. 

The tip mount is 80 millimeters long and 28 millimeters wide at the leather side.  It tapers to 20 millimeters at the finial.  The finial is a doomed brass cap brazed to the mount.

Speculation and questions

At this moment, it is believed that the tip mount of the displayed example is a replacement from a Type 4 scabbard.  The time frame of the replacement and what the original tip mount looked like is currently unknown.

The only observed example was found on a P.S. Justice T1B bayonet and it is currently believed to have been made for a P.S. Justice bayonet. The period of production is most likely early US Civil War (1860 to 1861).  

This variation is almost identical to Scabbard Type 3, Variation H, except for several minor details other than the tip mounts.  The location of the frog stud and the rivets show a small variation but the overall width of the leather body is much narrower on variation I (41 to 29 millimeters) than that of variation H (43 to 35 millimeters).   Shrinkage is a possibility but the overall feel is a leaner and keener body for the variation I.  Solving the tip mount question on the variation I may help answer this question as well.  Certainly they were made by the same manufacturer.
