The roll I've got is Telko Telcolor CN20 (is whats printed on the backing paper). It's got marks all over it, and kinda breaks apart already, very old, but the guy found it in a relatives place, so whatever faint terrible image I can get off will be quite valuable to them.
Can you put the formulae on here, please. (Got one or two ancient films from my Dad's time....nothing valuable, but always thought that I'd try to get around to attempting to process them one day!).
