Does anyone have any knowledge or technical data on "Special Color Duplicating Film SO-271"?
AFAIK this film was made by Eastman Kodak Company in the mid-sixties and was available in sheet film format.
It might have been similar to "Eastman Reversal Print Film", a 35mm film which was marketed as from 1962. Or was it an experimental type of "Ektachrome Duplicating Film 6119" a sheet film marketed from 1967? Or completely different to these two films?

The S.O. prefix meant that it was "Special Order", and that Kodak could withdrawor modify the product without prior notice.

Any information on this film gratefully received. MT
