FWIW, my bottle of Rodinal lists development time for old FP4 as 9

You can probably therefore take whatever time Ilford "Plus" developer recommends for FP 4 Plus and increase by about 50 percent and be in the developmental ballpark.

Can anyone provide me with suitable development times for Ilford FP4
using Ilford "Plus" developer? I have a really old "mystery" roll (ie
it
is FP4 and not FP4 Plus!!!). NB it is 35mm, spiral tank, 20C etc.
Thanks!
Peter.
Old thread I know, but Mass Dev Chart cites 9 mins for FP4+ and not 6……… Can you clarify please as I too need to develop some ‘old’ FP4 in Rodinal.
