  Selectol is discontinued but was identical to the published Kodak formula
D-52. An even softer developer can be made with Metol only. The following
is Agfa/Ansco 120, probably very similar to Kodak Selectol Soft, which I
believe is also discontinued. 

Ansco 120
Water (at 125F or 52C)				750.0 ml
Metol							 12.3 grams
Sodium Sulfite, dessicated			 36.0 grams
Sodium Carbonate, monohydrated		 36.0 grams
Potassium Bromide					  1.8 grams
Water to make					  1.0 liter

Dilute 1+1 for use. 

 An even softer working developer can be made by substituting Sodium
metaborate for the carbonate.
