Brookes can be identified by the presence of at least one band of wrought iron at the breech and a rough-finished, tapering barrel.
[4] Brooke reported fourteen single-banded 6.4 in (163 mm) rifles were completed by 8 January 1863, although Tredegar records list only eleven as some were double-banded before being shipped.
Two others were mounted on the broadside of the ironclad CSS Atlanta and survive today in Willard Park of the Washington Navy Yard.
[5] Double-banded rifles were produced from 28 October 1862 by direction of Stephen Mallory, Confederate Secretary of the Navy.
[1] On September 29, 2015, an archeological team from the University of South Carolina recovered a 7-inch double-banded gun from the CSS Pedee.
[11] S96, which was mounted at Fort Sidney Johnston on the Tombigbee River, is currently displayed in front of the city hall of Jackson, Alabama.
These were 15 inches (380 mm) longer than the other 7-inch rifles and were unique among Brooke guns in that they lacked cast trunnions.
One was mounted on the CSS Richmond and another was sent to the harbor defenses of Charleston, South Carolina, where it remains as a trophy in Ft.
[15] Brooke designed a series of smoothbores that were produced in small numbers by the Selma and Tredegar foundries.
The former were solid cylindrical projectiles with a blunt or flat nose to reduce the chance of a ricochet, and were often referred in contemporary accounts as "bolts".
They were filled with black powder with a fuse set to detonate a variable amount of time after being fired.
