Rifled artillery projectile, Parrott design, Federal manufacture, bursting shell, "case shot", lead balls packed in sulfur matrix, wrought iron sabot, Parrott time fuze without a flange, Parrott 10 pounder rifle, 2.9in. Projectile was manufactured in the Federal arsenals following the prewar invention of Robert Parrott and John Read working together. The sabot system utilized was a wrought iron ring, referred to as the "Type I" sabot, rifling was precast with three flanges, because it was too stiff to take the rifling otherwise. Some of these shells were configured as case shot (approx 9.5lbs to 11lbs. with balls ), or as "common" (approx 8lbs. to 9lbs. without balls). This shell is " case shot", explosive charge with lead balls, and with a time fuze was designed to detonate above the heads of troops in the open field. The lead balls are rough cast around .69 cal, packed in sulfur matrix near the top of the shell, powder packed in a long channel which expands near the bottom, on detonation the concentrated powder at the bottom was designed to burn the matrix and propel the balls and fragments forward. Fuze employed was a Parrott zinc time fuze, typically the pattern without a flange, Jones, Fuzes, pg. 76, edge of the fuze hole is milled thin. Bottom of shell usually shows a casting sprue which was rough milled, there will often be casting flaws near the base. Projectile measures: diameter 2.85in., length 8.375in. (excluding fuze), weight 9.5lbs. to 11lbs. Research Center: Artillery4617-Parrott, Ref: Dickey & George, Field Artillery (1993 Edition), pg. 216.
