The earliest Super-X shells would have been loaded with DuPont Number 93 as the Super-Fox brochres mention or a progressive burning powder that Western produced themselves as their literature of 1922 suggests -- "Guided by our experience obtained in manufacturing propellant powders at our smokeless powder factory during the war, we successfully developed and applied progressive burning powder to shotshell ammunition for the first time in the history of the industry, resulting in offering to the public the
Super-X load." The earliest style Super-X box for the 2 3/4 inch load in a Field shell --
When they brought out the 12-gauge 3-inch Super-X load it was put up in their Record shell --
As I said above, these early shells would have had a regular nitro card overpowder wad and normal wads between that and the chilled shot. Then by July 1929, you got Nash's beloved Lubaloy (Copperized) shot for extra cost over the regular chilled. Then circa 1931 Non-corrosive priming was added. Between April and September 1932, the Seal-Tite wad was introduced, replacing the conventional wads. By March 1934, the one-piece box. By March 1935, the Super-X was in its own steel-locked shell with a Super-X headstamp rather than the Field headstamp, but 12-gauge 3-inchers were still in the Record shell.
By 1947 Western has added the Seal-tite base wad and replaced the over powder card wad with the Super-Seal Cup Wad. By 1948 the Super-X shell has the Super-Seal crimp. Jim, I see your post WW-II box shill has RECORD between the top of the X on the face of the box.
