Parrott projectile

Parrott projectiles were rifled-artillery shot, shell, case shot, and bolts associated with Robert P. Parrott's gun system. Their expanding base cups or rings and numerous caliber and service variants make precise construction-level classification essential.

Also known as: Parrott shell, Parrott shot.

Family-level classification

Parrott is a design-family attribution, not a complete object description. Catalog records should state both the functional type—shell, case shot, solid shot, or bolt—and the Parrott-system attribution, then record caliber and base construction.

Patent and procurement evidence

Parrott's August 20, 1861 patent documents a projectile for rifled ordnance. Congressional and Ordnance Department records add contract, quantity, caliber, inspection, and dispute evidence that cannot be recovered from the patent drawing alone.
