Found two partial rolls of Plus-X approximately 25 years past expiration in an old camera case. I used the Kyocera-Samurai-X3 - which sets ISO automatically. Souped in Rodinal @ 1:50 for 13min @ 70-degrees. Literally what was recommended ny the Massive Development Chart, except the two degree warmer temp. The images are barely visible on top of a gray fog. The straight at ya flash didn't help either.
