Thanks for everyone for the feedback! I should have explained further that I was planning on making use of the old Rodinal for practice with test negatives so that I could get used to working with developing tanks and rotary processing. However, with some of the feedback above, it seems to me that I would run the risk of possibly creating problems for myself in the results. I wouldn't want to be getting substandard results and not know if it was the development technique or the chemistry, or both. Time is precious enough without making things more complicated. So, just need to figure out the best way to dispense with the old chemistry. Where I live, we do have a household hazardous waste disposal day later on this year. Since I have to take some items there as it is, it wouldn't be any extra work to include the older chemistry.
Thanks,
Ed
