The 1923 and 1925 Super-Fox brochures talk about the shells used in testing being loaded with DuPont De Luxe and DuPont Number 93. They then go on to say that -- "Unfortunately, De Luxe powder, the greatest shotgun powder that has ever been developed, is not now available to the public. It is not being loaded by any ammunition concern, and will not be sold to individuals--for which state of things we express sincere regret. However, Number 93 is a nearly similar powder in its action, and this propellant is being loaded by one of the great cartridge companies." They then show a Western Super-X pattern.
DuPont must have come up with a problem with De Luxe? At any rate, by 1928, all the talk is of DuPont Oval.
