Apparently a difference of opinion regarding "Swedish Iron" wink It should be noted that Swedish iron ore was one of the few sources for low phosphorus ore.

Appleton's Dictionary of Machines, Mechanics, Engine-work, and Engineering, 1873
“It would be difficult to define what scrap iron is, or what it is not, being composed of everything in iron that has previously been manufactured, as well as of the cuttings from the various manufactories…saws and steel pens.”

“Swedish iron, known by the mark CCND, and coach-springs, form an excellent combination for Damascus barrels.”


Appleton didn't have that quite right. CCND was Russian iron from Demidoff's Works at Nisch-netagilsk
