Just as we have seen photos of Spencer carbines bearing Thai and Cambodian markings, in 1865 after the fall of the Confederacy, the former Confederate superintendent of the Macon Laboratory, James H. Burton, who, from 1855 to 1860 had served as chief engineer at the Royal Small Arms Factory at Enfield Lock in England, left the United States to complete the installation of the new machinery for making the machine-made government pattern Enfield at BSA's new armory at Small Heath, afterwards took a contract to oversee the installation of new machinery at the Russian arsenal at Tula to manufacture the Spencer. Now, those would be some rare Spencers!
