If the film in the camera is over 70 years old it is gone. I am not an expert on this matter, but I think the chance of developing a negative 70 years old that will have any recognizable features in it is slim. The dates on film state that they will expire in a year or two. I have used films past the expiration date by maybe as much as six months. You will get something from a film 6 months old, but 70 years, come on! I would not waste any money trying to develop it.(posted 9481 days ago)
