I've recently found a roll of Kodak 116 film. It's unexposed it seems as the label is still on it. The label says Panchromatic Kodak XX. I was wondering when this film was made, if I could still shoot it, the ASA/ISO of it, etc.
I have a roll of Super XX Pan film in 616 size that expired in 1953. It lists a speed of 100 using American Standard Exposure Indexes. I'm too young to be familiar with that speed rating but I believe that that original rating would have been equivalent to a current ISO of 200. Sixty year old film would, however, have lost a fair bit of speed.
This thread has a fair bit of discussion about Super XX Pan film: (there was a url link here which no longer exists)
The development information I have for it (in my 1977 Kodak Darkroom Dataguide) refers only to sheet film, and recommends 8.5 minutes development at 68F in HC-110 dil B.
I would assume from the listing in the Dataguide that Super XX was no longer available in roll film by 1977. Certainly that style on backing paper looks older than anything I ever used in 1977.
I have a 1965 Darkroom Dataguide and even it lists no Super XX Pan roll film. Expiration dates mentioned elsewhere seem to be in the 1950s.
A Google search turned up a thread on RFF where it was discussed and there was talk of shooting it with a stop or two more exposure and developing in HC110 which tends toward less fog. But it didn't read as though anyone actually did it.
Your first problem might be do you have a camera that takes 116 film -- that's pretty big stuff!
