I have 10 sheets of Polaroid type 55 P/N sheets film left over from a project that ended about 2 years ago. The film has been in my freezer since I bought it new. I also have a negative clearing tank made for this film. I never used the tank. It contains instructions, the film holder, as well as the Sodium Sulfite needed to clear the negatives. It would be fun for someone who wants to experiement. The picture is of the clearing tank, the film is still in a deep freeze
