"Stub Damascus" is a historically dated term. It was used by both W. Greener and Henry Wilkinson in 1841 to describe horse-nail stubs (iron) mixed with coach spring steel, fused ("puddled") into a "bloom of iron", then hammer forged into rods which were then twisted prior to being wrapped around a mandrel and hammer welded, but with various descriptions thereafter. From Game Guns and Rifles by Richard Akehurst, 1969 "Stub Damascus"...was made from a quantity of old files, heated red hot and rendered hard and brittle by quenching in cold water, after which they were pounded to the size of No 5 shot and a proportion of 15 lb of these added to 25 lb of stubs. The mixture was fused together on the bed of an air-furnace, hammered to condense the metal and rolled into rods 3/8 inch square. These rods were twisted and treated as for Damascus, the effect being of a mottled twist. From Appleton's Dictionary of Machines, Mechanics, Engine-work, and Engineering, 1873 "Stub Damascus is merely one square rod of Damascus iron twisted and flattened into the riband for forming the barrel." W.W. Greener seemed to use the term for any British damascus barrel, using the terms One, Two, and Three Iron and Best "Stub Damascus" as late as 1907. No "Stub Damascus" barrels were listed as tested in the 1891 Birmingham Proof House Trial
