Just in case I can't get ready-made mixes, when I'm in Libya perhaps, here are the actual chemicals (I'll need more research to get the proportions).
a Developing Agent: Metol or hydroquinine
b Accelerator: borax or sodium carbonate or sodium hydroxide
c Preservative: sodium sulphate
d Restrainer: potassium bromide
potassium alum (hardener)
Also, a hypo eliminator, and a wetting agent.
