Haven't bothered to compound any of the formulas yet, but I may just wake up one day and place an order for some of these raw chemicals It also has formulas for certain other chemicals [uranium toner, anyone?] The only problem is......a lot of the units are denominated in grains.....don't think there is a modern scale that measures so accurately....

Does that Agfa book have color formulas? CN17 or Whatever develops Negative Ultra K film . Also color reversal film like ORWO color film that's transparency film?

I need both formulas to develop some film, I do have a C-41 instruction that supposedly works at 20° temps but I would prefer to use the original formulas.
