Reference to those films must make the cans around 40+ years old, so I don't think that you're going to get a reliable verdict as to whether it will still work.

If you want to give-it-a-go with a test film, for "old times sake", why not....you'll still have the empty cans as decoration, and, if you want to keep them long-term as Collectors Items, it may be best to avoid the risk of any remaining contents deteriorating and corroding them.
