It's probably my memory, but as I recall the pre-C-41 color negative process was C-21. Maybe it was C-22. I'll contact Rocky Mountain and set the record straight. Either way, it's probably what I'm looking for.
Thank you very much

My 1974 Kodak Color Dataguide lists C-22 and C-41 only. I wonder, did (does) Kodak have any little-known processes, or processes that lasted only a very sort time, particularly color processes?
I know of one other. One of the issues of Camera and Darkroom had the recipe for "K-14" which I think (don't bet the farm on this) was the process for the latest Kodachrome.
My! ... A truly involved, complex process. I would not recommend it for "home" use.
I do have something else - an intact Anscochrome Processing Kit, from the mid '60's. I have fond memories of this ... time has dulled the pain. Eleven little foil packets - mix them all up and comandeer the kitchen sink for a tempering bath. Sixteen processing "steps" - including the reversal exposure (two minutes - three feet from an R2 photoflood lamp - through a transparent film reel..). GALLONS and gallons of washing. The time necessary was something like three and a half hours...
