I have a Polaroid Back for a Mamiya 645AF with a pack of film. I don't know the condition of the back or film but the back looks in near perfect shape and the film was supposedly kept cold. I am asking $70.00 or best offer for this and shipping priority should be around $10.00 to the continental US. This back came with my 645AF and I really don't need it. I also have no idea how to use it. If you are interested in buying it, you can call me to walk me though how to use it prior to buying it to make sure it works.
