I am about to begin an endeavor that's probably hopeless, but I want to try. I recently was given a 2x3 Speed Graphic camera. Included were four film holders - all showing the black side of the dark slide. I checked them in a changing bag, and all have film in them. Inside the camera case is an unopened box of Agfa Isopan film with an expiration date of January 1945, so the film in the holders may be the same film with a similar expiration date.

I want to try developing the exposed film. I'm thinking of tray developing it in Pyrocat HD and developing by inspection. I could also try Rodinal. Anyone have any thoughts?

Thanks in advance,
juan
