Cleaning up my darkroom, I found a set of chemicals I was given some time ago and I can't identify it. It is a blank brown cardboard box (without the wrapping label) with 2 sacs in it.
One is a small sac (paper?) with a stamp:
MPHN 10 LTR c
Part A o
On the other side is printed: ID-11/Microphen/Bromophen and ID-11/Perceptol and ILFORD limited
The other sac is a much larger white plastic sac containing powder. It is stamped with:
PT - B
Can anyone tell what this set is for and how to use/mix it?
