I recently bought a Busch Pressman Model D 4X5 camera and the previous owner also gave me a box of Kodak 11" X 14" B&W film. He's not sure what kind of film it is and I can't find the information sheet that I imagine came with the film. The film is in a generic Kodak box without any obvious markings outside of the fact that it was made in Mexico (mostly in spanish). Unfortunately, when they opened the box, they sliced through the catalog number making that illegible. Anybody have any ideas how I can identify what kind of film I have? Does the film have some kind of identifying notches or something?
