I have a partial roll of 70 mm Portra 160 NC in 70mm. The film is late date, 2010 expiration. It has been cold stored/frozen since new. I do have the original can, however, I put it in another can as it has a lot of rust spots. I have tested a section of this film in black-and-white developer, and there was no perceptible base fog.
I weighed the can and there’s about 55 feet of film in the can still. That’s enough to make about 3.5 15 foot cartridges or 20 rolls of 120. This film is non-perforated.
Looking to get $175 for the roll, +$10 for shipping, but open to reasonable offers.
