Kodak RS Pan 6138: this film is weird

[MCB18]

I got a 60’ roll of this in 70mm that expired in 1964(!) when someone in TN liquidated a bunch of film. I have found zero information about this film other than one brief mention in a Kodak product catalog from the 1960’s. Apparently it was a 640 speed sheet film with extra red sensitivity. Why is it in a 70mm roll? I don’t know. It’s thick film, my slitter didn’t like it, it barely fit on a 120 spool, it made my camera’s motor drive scream… and yet somehow, I actually got results from it?! I’ll be honest I was expecting a completely fogged roll, but no, it actually has images. ISO 25 and 12 look pretty good I think! Very surprised just how well this film turned out. I have yet to scan them, but they look usable! Maybe even printable!

Interesting! Maybe some form of document copying film?

Too bad search engines are basically useless now for specific searches...

I very much doubt that, that type of film is very low speed and usually less red sensitive
