I hope your statement was meant to be sarcastic. People may not be aware of how old the E-2 process is and therefore how old this film really must be? Kodak discontinued the process in 1966 and the film must be older. Perhaps Harry Potter could use some trick like filmus repairus.
Thie film may be older than most APUG members.
I've been experimenting with gas-bleaching recently, seems to work. Characteristics altered, but fog-be-gone.
