This is an example of the long-pattern 20-pounder (3.67-inch caliber) Parrott projectile. The long-pattern Parrott projectiles are common shell and do not contain any case-shot material. A large number of this style projectile were fired during the 1864 Atlanta Campaign. This pattern is also found with a wrought iron ring sabot, therefore, would be considered a Read-Parrott projectile pattern.
