Hi all, Has anyone yet solved the mystery about FX14 Acutol Developer? It came out in the early sixties, and was very successfull. The RPS claim that the formulation was patented. I can find no evidence of this. It has long since been discontinued. The formula may have been a private arrangement between Geoff. Crawley, the inventor, and Paterson, the manufacturer. This situation is starting to assume the status of a state secret, but since the 20year expirey date for the patent has well passed, surely the freedom of information act would allow the formula to be exposed to the Public.
