Testing my 1968 MAMIYA Press Super 23 that I have not used for some years after I renewed the foam seal strips on the Rollfim Backs to see if they were light-tight, I just found a very old 09/1987 Kodak VR 400 film in fridge , rated it 50 ASA and wa amazed I got some images but with huge fog level
Yes, nice! And, it looks like both the Mamiya and the old film work fine. I love my Mamiya Super 23. Works well, very flexible with all the accessories, and keeps me in shape carrying it.
