There are a few Kodak Ltd (UK) developers not included in similar Eastman Kodak publications or the same era, some sold in packaged form commercially. D72 wasn't available in the UK in1944 or when I first began serious photography in the late 1960's instead we had D163 in Europe as a Universal negative and paper developer.

D158 Velox developer superseded the earlier Nepera-Velox developer which Koak published in 1905.


The Nepera Velox formula - as published by Eastman Kodak in 1905 is:

Hydroquinone 2 g
Sodium Sulphite (anhyd) 7 g
Sodium Carbonate (anhyd) 13g
Metol 0.5 g
Potassium Bromide 10% 40 drops
Water to 300 ml
