(Fyrberg) Chicago Long Range Wonder in the 1902 Sears, Roebuck & Co. Catalogue No. 111. "Our barrels are made for the highest explosive gun powders used, such as white or nitro powder...and could be used as safely as the regular black powder."
1908 Sears catalog No. 117
"Accidents from the use of high explosive ammunition, such as smokeless powder, are rendered impossible. After 10,000 shots from smokeless ammunition your gun is just as secure, just as solid, just as perfect fitting as before the first cartridge was fired."
