"Best Silver Steel Damascus barrels contain over 70% of the finest steel, and it is the systematic twisting and arrangement of the iron and steel bars, as they are welded together and beaten into a flat ribbon before being coiled into the form of a tube, that give the beautiful figure or pattern observed in a first-class twist barrel..."
"Laminated steel barrels differ but slightly from those known as 'Damascus.' The former were first made by Mr. W. Greener (senior), of Birmingham, about 1850, and were composed of three parts steel and one part iron. At the present time the best English damascus, as well as laminated steel barrels, contain over 60% of the harder metal, and there is little perceptible difference between Damascus and a laminated Damascus barrel, as both are of very similar workmanship and materials."
