I am going to test the 70-year-old Kodak Baby Brownie Special with a roll of Efke R 100 127. In another thread, it was said that B&W films really don't expire. The process-by date on this particular film was January 2000 or 2001. Where the film is this old, should any push or pull processing be done with the roll, in order to get visible prints from it? I'm not looking for anything perfect. Push and pull processing are options available from the lab I will be mailing it to. Thanks.
