I posted a similar question recently and received no replies. I've also contacted Fuji in the UK and they don't know the answers. I have some black and white 35mm film dating from the late '80s/early '90s which bears the markings 'Fuji 1600-PR'. Yes, I know this is 1600 ISO film. It has separately been suggested to me that the PR stood/stands for 'press' or 'professional'. Do you know what it stands for? Is this film the same as Neopan 1600? Also, the film identifier is followed by a three digit number, which is different on each roll of film. Might this give an indication of coating dates? Is there anyone out there who knows their Fuji better than Fuji does? Thank you.
