I teach traditional black and white film photography and a student just brought a bell & howell autoload 309 to me. It looks like it is in good working condition and his family still has the projector to run the film. What film can I buy specifically for him to use and more importantly...where can he get that film developed? And what battery can I buy to make it work. Thanks! Any other suggestions, input, etc on how to make it all work would be greatly appreciated as well.
