The Parrott rifles were developed by Robert P. Parrott, and patented in 1861. They were easy to manufacture, inexpensive, and accurate, so much so that the Confederates manufactured their own version of the piece. Parrott rifles are most readily identified by the wrought iron, reinforcing band that was shrink-fitted around the breech. There are two different versions of this artillery piece. The 1861 version, shown above, has a 2.9 in (7.37 cm) bore, while the 1863 version has a 3 in (7.62 cm) bore. The outward distinction between the two versions is the 1863's lack of a muzzle swell. The 10-pounder Parrott used shell, spherical case, and canister. The Model '63 could fire ammunition for the Model '61, but not vice versa.
