Rifled artillery projectile, Tennessee design, Confederate manufacture, solid bolt, medium pattern with blunt nose, bourrelet rings, copper disc cupped sabot with 3 studs in the sabot, Brooke rifle, 7in. Projectile was Confederate manufactured and was originally believed to have been developed by Mullane working with Read and others, however, updated research has not been able to confirm the existence of a man named Mullane. Period literature often refers to work as the "Tennessee" design, cup, or sabot, and is attributed to Captain Lardner Gibbon, although official recognition for his development was never granted. The sabot system utilized was a copper disc held in place by studs and secured with a center bolt, a manufacturing innovation allowing the parts made of different metals, copper and iron, to be prepared independent and assembled at the end. This sabot pattern, referred to as Type II, employed three studs cast into the sabot and fitted into holes cast into the shell body, secured by a bolt in the center. This pattern utilized two bourrelet rings, as a labor saving device, only the rings had to be accurately machined, the rest could be left rough , the top is only slightly rounded, this flat top was designed to deliver maximum impact against the Federal ironclads. This median length bolt was intended for the new rifled Brooke rifles. Projectile measures: diameter 6.9in., length 13.25in., weight 118lbs.
