I received a bulk load quantity of unknown 35mm photographic film, and in testing it to ID it, I've found that it is coded "A514", which doesn't pop up in Google at all. Running it through HC-110, it appears to be about ASA 25 or so. It feels a bit thick to me when I handle it. I speculate that it is movie film of some sort, but wonder if anyone else has come across this product?
