The Lefaucheux M1858 was a French military revolver developed for the navy, chambered for the 12 mm pinfire cartridge, and based on a design by Casimir Lefaucheux and his son, Eugene (also a gun designer). The 1854 model was the first metallic-cartridge revolver adopted by a national government; the 1858 was the first variant fielded[2] It was first issued in 1858 by the French Navy (as either the Lefaucheux de Marine mle 1858 or simply M1858), and though never issued by the French Army, it was used in limited numbers by the French Cavalry during their 1862 deployment to Mexico.[3] The 1858 was later upgraded in the late 1860s as the Lefaucheux de Marine 1870. It was accepted by the French Navy, but only 150 copies were delivered by 1872.[4] Models of the 1858 were also purchased by Spain, Sweden, Italy, Russia, and Norway. Most were produced either at the state arsenal in St. Etienne (MAS), Liege, Belgium, or local producers under license.[5] The revolver was sold to the civilian market as well. Most military models were produced only with single-action, whereas civilian models were made primarily with double action. Founds, in 1849, the firm ANCION & Co and merges with J. ANCION & Co in 1866. Originally Pinfire many were converted or manufactured from parts available. This gun was probably a production by the Ancion Company. Wiki ref
