It looks like the Super Ikonta A & C used a somewhat simpler mechanism than the Type 532/16. The Super Ikonta B has two prisms that rotate in opposite directions and driven by gear train by the large gear teeth on the focus ring for the front element. It is as David said, once the two prisms are aligned so that the range finder patch is to the left of real image, then one walks the adjustment a tooth at a time until they line up on the real image for a specific target. Mark the alignment of the prisms and the base plate. Then remove the prisms, set the focus ring and resinstalled the prisms to the alignment marks. It is much simpler than it would seem.
