Charles,
I do in fact see that Kirby still made the gray cord (#192059) with the red plugs on it post-1966, since I see the male plug on the second cord in the second picture (in reply #4) has the angular middle part that makes it look like the Classic III cord only with a gray cord body.
If one of those #192059 cords existed with the 1983-later male plug end (all square-cut, no curves), that would be quite rare.
Too bad the original 562 cord (cream body/sirocco ends) didn't make the transition.
