Again Andresen's One shot p-Aminophenol formulae from the early 1900's, you see people saying they are different Formulae, but the ratio of p-Aminophenol to Potassium Metabisulphte is the samev 1 part p-Aminophenil to 3 parts Potassium Metabisulphite with add enough Hydroxide to just dissolve all the developer.

There is also Rodinal Formula:
Water 100ml
Potassium metabisulfite 30g
Paramidophenol 10g
Add saturated sodium hydroxide solution until precipitate dissolves.

In the beginning of the book there are comments about chemicals:
Paramidophenol - this is p-aminophenol slat formed with HCl, so this is hydrochloride.
