The firm of R&R Sutherlands was a partnership between Richard and Ramsay Sutherland that worked in Birmingham circa 1800-1827. They received a contract from the British Board of Ordnance to produced trade guns for the Native Americans that were allied with the British during the War of 1812 and during the period of 1813-1816 the firm delivered 2,587 guns (Gordon). This percussion altered Chief's Grade gun with Board of Ordnance proofs was likely part of the War of 1812 contract deliveries.
