The 126 film... The brand is "Triple Print" I have a few in 126 and 127 myself and took me a while to track down what it was. On the label it says "can only be processed at X lab" so wanted to know why it couldn't be processed anywhere, well it's because it is a C-22 variant and isn't C-41 compatible for processing.
Yeah, C22 was the earlier process but why do you think it's "triple print" brand not Kodak/Agfa/Fuji etc.?
