Years ago, I ran a photography store where we offered same day C-41 and E-6 Processing. Long story, short, is that in 2002 when we "went digital", the 4E processor sat around until it was apparent that it was no longer even viable to sell, so it was discarded. I did happen to hang on to control boards and tanks, etc for "some day". With the resurgence of film, perhaps that day is here... See my other Wing-Lynch items.
