Thanks, everyone. I took Sirius Glass’ advice and off-loaded the film to a tank so I could examine the entirety of the backing paper — and there’s not another identifying mark on it. It happens that I recently developed a roll of Ilford FP-4+ and had kept the backing paper in case, you know, I decided to start self-cutting and rolling some 127 film. The FP-4+ paper is identical to the mystery roll, including not saying anything about the film or manufacturer — but it did have the glue strip still attached, which is how I know it’s Ilford FP-4+. Now for all I know Ilford uses the same backing paper for a variety of different emulsions, so the mystery roll may or may not be FP-4+. I’ll develop it as if it were, maybe push it a little in case it’s actually a faster film than ISO125, and keep my fingers crossed. Let’s see what develops....
