I don't think so. As I said, Kentmere is one of the possibilities. My money is rather on Efke 25.
Kentmere/Ilford Harman will not produce brandnew emulsions for other companies, let alone for a company notorious for its rebranding, relabelling and its confusing market policies.
The factory producing Efke has been shut over a year now ...
What evidence do you have for those (contradictory) statements about Harman?
