Rifled artillery projectile, Parrott design, Federal manufacture, bursting shell, short pattern "case shot", narrow ring brass sabot, Parrott time fuze with a flange, Parrott 20 pounder rifle, 3.67in. 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. 17.5lbs to 19lbs. with balls, short, 9.25in.), or as "common" (approx 15lbs. to 17lbs. without balls, long 10.25in.). 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. Fuze employed was a a Parrott zinc time fuze, typically the pattern with a long stem and flat top with a flange, an innovation to prevent gas leaks around the fuze causing premature detonations, Jones, Fuzes, pg. 77 upper right, 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 3.6in., length 9.25in. (excluding fuze), weight 17.5lbs to 19lbs. Research Center: Artillery4666-Parrott, Ref: Dickey & George, Field Artillery (1993 Edition), pg. 231.
