I'm not quite sure where this came from:

Kodak monobath film developer-fixer (1961)
Sodium sulfite 50 g
Phenidone 4 g
Hydroquinone 12 g
Sodium thiosulfate (penta) 110 g
Sodium hydroxide 4 g
Develop film 4 - 7 minutes at 23C (or until fully fixed)
To mix, add the Phenidone to the water, but do not mix. Add a pinch of the hydroquinone. Add the remaining ingredients in the order given, and mix to dissolve the Phenidone. Then add the remaining hydroquinone. Dissolve the sodium hydroxide separately in a small volume of water before adding it to the mix.
