I'm getting an old expired roll of Anscochrome in a lot of Verichrome Pan and Panatomic-X films that I really wanted. Should I save the old color film for display or is there any room temperature (75F) cross process to C41, E6 or B&W that I could do with it? I know 100+F C-41 or E6 would ruin it and imagine B&W would at least give me a silver image, 7 minutes in HC-110 dilution B I've read. Any other suggestions?
