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.
Webley &amp; Scott
In 1910 Webley offered a new automatic for testing, and in 1911 the Webley self-loading .455-inch Mark I was recommended by both the SAC and the Chief Inspector of Small Arms (CISA.) This pistol was adopted by the Royal Navy in early 1912 as the first automatic pistol officially in British service. Later the pistol was also adopted by the Royal Horse Artillery and was issued to members of the Royal Flying Corps.
