Back last year when I bought my Crown Graphic from a local photographer, he threw in two boxes of long-expired B&W 4x5 Polaroid film: Polapan Pro100 Type 54xp. 5/1997, and Polapan 400, exp. 11/1995. The pods are certainly dried out, but I'm wondering if the film itself is still viable. If so, could I peel and develop it myself in Rodinal, Caffenol, etc., or would I be completely wasting my time and should toss them? Thanks!
