Oh, and what film was a roll that was 130mm wide? Those are later than the ones that are 90mm wide (which are about 1912).

Companies made different bases at the same time, so making up such a list would be even more difficult.

The most recent date for a change I got was 1960.

Look at the still film format sizes

That should tell you about the roll film sizes...

Also, I'll try to shoot a roll of verichrome (non-pan) which PE ensures me is nitrite (or nitrate.. whatever the bas one is) base and I can mail you some to burn once I scan them.

No worries, Stone - some of mine are actually labeled nitrate and it's a reaction I'm fairly familiar with having burned some unburned gunpowder from contact shots in my day. Remember my job used to be forensic chemist. We used DPA and a match to test particles from clothing to see if they were unburned gunpowder.

Cool didn't know.
