Sorry, I also mixed up a little and left out information. The color of my car's running board cover is (of course) Battleship grey, a linoleum most probably delivered from the Armstrong Cork Products Company (or Sherwin Williams company, the two leading makers at that time.)
More info:
http://www.scripophily.net/arcocope19.htmlArmstrong linoleum was (and still is) on the market from 1909. The owners achieved position as marketleaders and got good connections to other leading US-industrialists during these 100 years. (Example: as you may see here)
In 1952, a group of leading industrialists that included Alfred P. Sloan of General Motors, Frank W. Abrams of Standard Oil Company of New Jersey, Henry Ford II of Ford Motor Company, John L. McCaffrey of International Harvester, Irving S. Olds of United States Steel Corporation, Henning W. Prentis of Armstrong Cork Company, and Laird Bell of Weyerhauser Timber formed the Council for Financial Aid to Education, which increased corporate gifts to colleges from $24 million annually to $136 million annually over ten years.
Luckily we can get the "same" material and color on running boards to our 490s, even today.
