If I'm recalling correctly, there was one beam splitter, and one bi-pack, with the cyan negative behind one of the others, which is why reds are always soft, and imprecise as to registration.
The liquid dyes would cover the problem, as the overall image was soft.
I believe this is a new digital combine from the original nitrate negs. Do you recall dupe replacement sections or safety B roll when the analogue work was done?
