Hand stitched leather, 5 3/8” length plus the plug. Bag form with horn spout. The leather secured with home spun cord. The original wood stopper encased in tattered cloth strips. See Collector’s Illustrated Encyclopedia of the American Revolution, Neumann p227, top, center for a very similar example lacking the stopper. These were used to carry large shot which was loaded with the ball (“buck and ball”) to increase the effectiveness of the load. Its slender form allowed it to be tucked in the belt or pouch. That it is not a shot container for fowling (shot gunning), is demonstrated by its very limited capacity. It would barely provide four to five charges for a shotgun but enough shot for perhaps 25 buck and ball loads. Wonderful dry untouched condition and complete, with some original shot within.
