wow, your PLI states that it was for both ...!
i have a PLI from the 40s and it only states it as a paper developer
and mentions ansco 125 for film.
depending on the age of the developer, i have used dilutions from anywhere from 1:4 - 1:10 or so. i develop by inspection, so, it makes things a little easier.
i hope juan is reading this - maybe the mystery of "gaf universal developer" has been solved! <g>
good luck with your tests tom
