Mike, interesting about the walrus hide. About 30 years ago,I found a book on manufacturing Winchesters at the Winchester plant. It showed a picture of the polishers and the wheels looked to be about 2" thick and maybe more than 30" in diameter. It described them as being made out of rhino hide. Totally agree on the nickle content of the receivers. It was the carbonia or gas bluing that caused the flaking.
