Try contacting Sprint Chemicals. I don't have their address at hand but I
have purchased their chemicals from Maine Photographic Workshops. They make
reversal chemicals which I have used successfully with TMX. It would likely
work with FP4.
Also, in one of the "second tier" photo mags (it might have been Darkroom,
before they changed the name) about 1992-1995 there were some articles on
reversal processing. Sorry I can't be more specific here but.....
If you don't have any luck locating this material, let me know and I will
find my archive of old mags, strange information, etc (it's been M.I.A.
since a move but I think I can locate more specific info if you need it.)
