Thank you for noticing the error in the formula I posted. The amount of TEA in the formula should be 120 ml, not 12. The Photographers' Formulary formula is slightly different. As posted on their website, it is:

Metol 17.8 g
Oxalic Acid 1.7 g
Potassium Metabisulfite 4.3 g
Sodium Sulfite 140.0 g
Pyrogallic Acid (Pyro) 51.2 g
Triethanolamine 133 ml
Water to 4 liters
