I finally shot a roll of Imation Scotch Chrome 400 ISO which expired in 1999. Supposedly the film is re-branded ferrania film stock. I bought 20 rolls of the stuff (ten 100 ISO and ten 400 ISO) from ebay a couple weeks ago.
I exposed it at 200 ISO seeing as how it expired more than a decade ago. Cross processed in Tetenal C-41 developer yielded usable negatives. You can see this film has not aged well but that's why it looks so cool!
