Short answers, pulled from the story.
The London Armoury Company was a British arms manufactory founded on the 9th of February 1856, in the Bermondsey section of London. Its factory occupied the former site of the South-Eastern Railway Company. It operated until it dissolved in the spring of 1866.
The principal shareholder was Robert Adams, inventor of the Adams revolver. His cousin James Kerr was another important stockholder. Kerr later became the dominant figure after Adams sold his shares and left the company in 1859.
The London Armoury Company was the major arms supplier to the Confederacy during the U.S. Civil War. It manufactured and shipped more than 70,000 rifles and about 7,000 revolvers to the South, contracted through Confederate buyers Major Caleb Huse and Captain James Bulloch.
The company produced the Kerr Patent Revolver in .36 and .44 caliber, and manufactured the Enfield 1853 pattern rifled musket under British government contract. It shipped more than 70,000 rifles and roughly 7,000 of its approximately 10,000 total revolvers to the Confederacy.
The company was almost completely dependent on sales to the Confederacy and survived for only a year after the end of the Civil War. It dissolved in the spring of 1866 once its principal client no longer existed.
Most of the gunsmiths and staff went on to form London Small Arms Co. Ltd in 1866, the same year the Armoury dissolved. The London Armoury Company name was later revived during World War I to import arms from America, including the Colt New Service Revolver in .455 Eley.
