The Parrott rifles were developed by Robert P. Parrott, and patented in 1861. They were easy to manufacture, inexpensive, and accurate. Parrott rifles are most readily identified by the wrought iron, reinforcing band that was shrink-fitted around the breech. The 3.67-inch Navy Parrot is the naval version of the 20-pounder Parrott; the difference being that the navy version has rings at the base of the breech to accommodate handling on the deck of a ship. The 3.67-inch Parrott used shell, spherical case, and canister.
