Hello,vi was given two rolls of this stuff as part of a bundle deal I bought from a local guy. A roll of 400 iso that expired in 02(made in Italy), and 200 expired August '00 (made in Germany). I'm 99% sure the 400 is c41, the back was brown, not black, bit the 200 stuff I loaded before I knew it was different, or how to tell. That roll is done, and I've found a sheet that lists various codes(appears to be from a lab) saying these codes are c41, and these codes are ecnII, but neither the codes listed on my canisters are on the list. The 200 iso one has 5400.2 on it. Any ideas? I'm aware it's not the greatest film, the pictures I took I don't much care about, and I do have a local lab that can develop either. But... I GOTTA KNOW!
