Metol...........................2,5g
Sodium sulphite (anh.).....100g
Hydroquinone................5g
Borax ..........................2g
Boric Acid.....................15g
Water..........................1litre

Kodak publish quite a few variations of D76 in the 1930's Grant Haist would have been aware of the original EK Research fine grain developer, Troop wasn't

I noticed on Ian Grant's web site several Kodak variants with only a little borax and quite a lot of boric acid, including this one (above). I wondered why the pH wouldn't be too low for normal development. Were these for a particular purpose?
