I shot some 8x10 Dupont X-F Pan from the 1940s recently that smelled strongly of vinegar when I opened the box. Sure enough the base had shrunk so much that it wouldn't fit into an 8x10 holder properly, so I taped it in. I had ZERO hope of there being an image, but before I tossed it I wanted to be sure. To my surprise I achieved the result below. How archival it is from here on out only time will tell.
