Today I picked up two Ilford xp1 rolls (one 120 roll dated 1982, and an undated 35mm roll, but it's almost certainly about the same age). the thing is, I remember reading a couple years ago that xp1 didn't have standard c41 dev times, and xp2 was developed in response to this. So my question for you all would be- what speed should I shoot this at to have it processed normally? (also I have no idea how this was stored.)
