I just was given two boxes of unknown material, someone found on the attic of a primary school. I also got some boxes of old Brovira en Portriga paper, which was all badly fogged.
The first is a box of Ilford Formolith SP4, 24 x 30 cm. I took one sheet out of the box in total darkness and it seems to be some kind of graphical film. Is there any use for it in a normal black and white darkroom?
The other is is an envelope of Veribrom N2 paper, 30 x 40 cm. I did a fogging test on it and it turned black, unlike the Agfa Paper, which was a dirty grey. Is this somekind of reversal paper, that should be processed in the dark?
Any information would be welcome.
