Rifled artillery projectile, Parrott design, Federal manufacture, bursting shell, "case shot" lead balls packed in asphalt matrix, narrow ring brass sabot, Parrott time fuze with a flange, Parrott 10 pounder rifle, 2.9in. Projectile was manufactured in the Federal arsenals following the invention of Robert Parrott. The sabot system utilized was a narrow brass ring secured to the base with internal rabbets, referred to as "type III", more flexible than wrought iron and more narrow than the high band, this took the rifling much better than the earlier designs. 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 case shot balls are rough cast around .69 cal, packed in black asphalt 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 a Parrott zinc time fuze, typically the pattern with a rounded top and flange, an innovation to prevent gas leaks around the fuze causing premature detonations, Jones, Fuzes, pg. 77 upper left, edge of the fuze hole is milled flat. 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: Artillery4636-Parrott, Ref: Dickey & George, Field Artillery (1993 Edition), pg. 226.
