That's also why you could "Cross Process" C22 (kodacolor-X) in E-4 or E-4 (Ektachrome-X) in C-22 for artistic effects.
You can do a similar process today exchanging E-6 & new Ektachrome emulsions in C-41 & vice versa.
Never try C-22 film or Ektachrome-X in modern chemistry though the emulsion will be stripped from the backing in development! wrecking the film & killing the chemistry & processor's filters too.
