The 13-pounder was the last Rifled Muzzle Loading field gun to be produced, with production starting in 1879. Unlike the 9 and 16 Pounder RML guns, the 13-pounder had a much greater muzzle length. They could be finished as muzzle loaders or breech loaders, however they were all ordered to be finished as muzzle loaders. [ 1 ]
The RML 9-pounder 8 cwt gun and the RML 9-pounder 6 cwt gun were British Rifled, Muzzle Loading (RML) field, horse and naval artillery guns manufactured in England in the 19th century.
