Here are the some test results from a very expired Ilford 4x5 I got from evilbay few weeks ago...not bad at all considering the film is 50 years old!
They were vacuum sealed when arrived and I believe it helped to store them in great condition as they're not fogged or faded, the grains are not noticeable either.
The film is the FP3 125 and I followed instructions to process as if it was the FP4, pre-soaked for a couple of minutes and then processed using Rodinal 1:100 in my Combi Plan. The developing time was increased from 20 to 28 minutes, inverting the tank continuously for the first minute and then one very gently inversion every 30 seconds.
The images were scanned at 1200 dpi and I only adjusted levels and curves, no sharpening. I enhanced some details so they can be better seen, normally you get to see the grains especially on the sky area but on these ones they're almost unnoticed.
The little spot on the top left corner of each negative is in fact a tiny hole, probably to make easy to hang when drying...
