I think the modules' layout must have varied over time (and perhaps their designations as well?). My mono input modules (which were loaded in the console when I bought it) look exactly like Bill's first link. The two NOS stereo modules I bought from a PA hire company in Quebec look more like the Soundcraft site photo, with the 6 auxes all having separate pots, although with only 3 bands of EQ.
They all fit interchangeably in all 200 series frames AFAIK, and my manual (downloaded off the SC site) describes many other channel variants that I have never seen in pictures or in an operational console (including phono preamp and Sowter input transformer options and sound reinforcement 'matrix' type strips).
This is somewhat speculative, Jim Williams could probably provide a much more definitive answer.
