So, do you know, did all of the emulsions that Kodak made up until the "big kill off" (when they axed "Verichrome", "Ektapan", "Commercial") -- which seemed to coincide with the cut over to the "new coating plant" -- get 'made over' to the Modern methods or were these still Recent recipes at the time they were discontinued?

I'm presuming that PX and TX got "Modernized" at some point, due to their relative popularity.
