Pre-war (the second one) Plus-X
I have similar film inherited from an uncle who passed away ten years ago. Most of it was taken in the 1930s on Plus-X. It was stored rolled into the original metal cans left for decades in a closet in upstate NY. The cans prevented humidity from damaging the film.
Of course it too has quite a strong curl, but can be handled without cracking. I cut the film into strips and put these into archival sleeves that I pressed under some books for a few weeks. Maybe decades would be better? The film still has substantial curl but the strips can be printed or scanned. I had to use small pieces of tape to hold it flat enough for the Nikon 9000 scanner to capture it in between its plastic frames. For printing it can be handled in a Bessler glass-less carrier.
A bigger problem came about when making images from the film. There are a LOT of dust and spots that cannot be removed. Some of the films were severly under exposed (remember that there were no cheap light meters in those days) making it nearly impossible to print analog. Washing might help with dirt and spots, but then it could also destroy some of the images and I didn't have the nerve to try that.
I resorted to d*&^%$al corrections and got acceptable renditions. Here is an example taken in 1939 in Washington Park, Albany, NY.
