Gone through my other books and found the one: Laubert, Photographic Formulas and Tables, year 1917, 3d edition.
There is also Rodinal Formula:
Potassium metabisulfite 30g
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.
