I think there is something wrong in the numbering, film developers had numbering 210-230s, paper developers 250-260s. So it maybe 233?
The only one I've found that is close is G212
* Water, 125F/52C 750 ml
* Metol 2 g
* Sodium Sulfite (anhydrous) 25 g
* Hydroquinone 1.5 g
* Sodium Carbonate (monohydrate*) 35 g
* Potassium Bromide 0.5 g
* Cold water to make 1L

Given the amount of Metol, this should be quite vigorous? or am I wrong?
