This is thought to be
an early experimental Parrott projectile. The lead sabot differs from that of the
solid shot specimen. The pattern pictured above has a rounded base compared
to the concave base mentioned. The concave base probably expanded into the rifling
too much and the rounded base was developed from this trial. The 1 7/8" tall
lead sabot has three 1.42" wide flanges that correspond to the 10-pounder (2.9-inch
caliber) Parrott rifling. A Parrott zinc time fuze plug screws easily into the
fuze
threads.
