The 3-inch Ordnance Rifle, also known as the ordnance rifle, the ordnance gun, and the Griffen gun, was invented by John Griffen, superintendent of the Safe Harbor Iron Works in Pennsylvania, and its initial design was built by the Phoenix Iron Company of Phoenixville, Pennsylvania, which manufactured most of the 3-inch rifles used in the Union armies. Griffen developed a process in which strips of wrought iron 3/4 inches thick and 4 1/2 inches wide were wrapped around an iron core by a lathe, then the tube was heated and rolled to a length of seven feet before trunnions were welded on and a bore was reamed out. This made the 3-inch Ordnance Rifle the lightest gun in field artillery service during the Civil War, yet also the strongest and most durable in the field because of the wrapped wrought iron bands around the core. It was deployed in support of infantry to repulse enemy assaults, often positioned behind the lines and fired over the heads of friendly troops, and its range made it excellent for long-range shelling, though its use was limited in wooded areas while remaining accurate and lethal in open spaces. The rifle at Lonoke County Courthouse was brought there before 1911 through the efforts of John Hallum, a Civil War soldier and one-time lawyer in Lonoke. Local stories hold that it was used in the Brooks-Baxter War of 1874, that it was taken from Federal forces and hidden in a bayou, and that it was nicknamed the Lady Furlow, and it was restored in the 1920s in a blacksmith shop across from the courthouse. Little documented history of Rifle No. 705 can be found, but guns of this type were in the area from September, 1863 to 1865, deployed by units such as Battery K, Second Missouri Light Artillery (U.S.) and the Twenty-fifth Ohio Battery (U.S.) in the Little Rock Campaign, including Brownsville and Reed's Bridge. The Hotchkiss Shell, weighing 9.5 pounds with a powder charge of 1 pound, a range at 5° elevation of 1,830 yards, and a muzzle velocity of 1,215 ft./sec., was invented by Andrew Hotchkiss of Sharon, Connecticut, and patented October 16, 1855; this example lacks its sabot and its concussion or percussion fuze, and rifled artillery technology produced this new kind of projectile, while a 3 Inch Shenkle round was also used under certain circumstances.
