Cooke Cine-Varotal 25-250 Mk-2 zoom converter reassembly 

I recorded this video back in '88 for my fellow techs at Victor Duncan Inc.... It is a training video and it is long so for that I do apologize but if you are working on one of these it is a worthwhile watch.
The (VHS) video tape it was digitized from is older than I was when I did it.... RU-vid before it was RU-vid!
