    I've come across an old roll of 35mm FP4 (before it became FP4 Plus). Does
    anyone know any processing times for the film?

    Ilford suggested the following starting times for ID-11 or D-76
    at 68 degrees F. Exposed at ISO 125. Intermittent agitation of 10 seconds
    in every minutes.

    Not Diluted 6 1/2 minutes
    1+1 9 minutes
    1+3 15 minutes

    Other developers:

    1+7 ISO 125 5 1/2 minutes

    Perceptol or Microdol X:
    none ISO 64 10 minutes
    1 + 1 ISO 100 11 minutes
    1 + 3 ISO 100 16 minutes

    Ilford's note:
    "These developing times may be increased up to 50% for additional contrast
    when using diffusion or cold light type enlargers."

    Hope this gets you going.
