I associate the first CDU as being used with Litton INS, I have never seen the two later CDUs. I worked with multiple operators over the years until I retired in 2008. And would expect to find that equipment on DC10-10 and -30, Tristar and 747 2/300.
Concorde which you mention was as far as I am aware Carousel equipped.
Carousel was a quite common fit to Tristar too. Litton more usual on DC10 and 747 but as ever the fit was an operator option.
I do remember the INU being heavy !
