Hi Jerry, 70mm was often used by pros shooting weddings and portraits. I have a 70mm Hasselblad back, and I'm sure other medium format cameras used it. Also some aerial cameras used it. You certainly could try clipping off some film and developing it in B&W. I don't know if that would work, but I believe you would get some image out of it. Maybe in the 10 min development range. It would be fascinating to know why the film was never developed. The cassettes are pretty standard for 70mm.
