Volley gun
Two notable artillery-sized volley guns were developed in the mid-19th century, although neither was particularly successful in practice. Developed in the 1860s and based on an 1850s design by a captain Fafschamps, the French mitrailleuse is an example of a multi-barreled volley gun that could fire all of its barrels simultaneously or sequentially over a short period of time. Also developed in the 1860s, General Origen Vandenburgh of the New York State Militia designed a weapon that had eighty five parallel .50 caliber rifle barrels. After failing to sell the weapon to the United Kingdom, he reportedly sold a small number to the Confederate States of America, although there is no record that they were actually used. One Vandenburgh gun was located at Fort Fisher, North Carolina, and another reportedly at Salisbury, NC.
Ethan Allen (armsmaker)
This is the first cartridge revolver made by Allen and Wheelock, and one of the first cartridge revolvers from any manufacturer (competing with the Smith and Wesson model 1). It is a single-action seven-shot revolver in .22 Rimfire (black powder equivalent of the modern .22 Short). It features the side-hammer of the early percussion revolvers and a spur trigger. Empty cases were removed by removing the cylinder, and using the cylinder pin to push the case out of the cylinder. There are many variations typically organized into six models, though all share the size and critical design features. Most were made with a 3-inch barrel. The first through fourth models have engraved cylinders, with crossed rifles, a horse and rider, military articles, an Indian with bow and a sailing ship. Allen obtained a patent granted in 1858, and it is likely that production began in 1857. Production continued until 1863, when production of all cartridge revolvers was halted by the lawsuit described previously. Production resumed upon expiry of the Rollin White patent in 1869, though likely from parts manufactured in the earlier period. After Allen's death in 1871, production continued for some period under the new company name Forehand and Wadsworth.
