Default MK 35 formula for thin-emulsion films

Here is the other formula I got from '35mm Photography Magazine' in the 1960's. It is for thin-emulsion films such as KB14 and Pan F: it is really a one-solution Beutler but handy to mix up even 500mls as I do in small bottles and controls the contrast of KB14 especially in sun-lit conditions. For copying I have used recently Crawley's Acutol S (FX15) formula diluted 1+3
Metol 5gms
Sodium Sulphite anhyd. 25 gms
Kodalk 50 gms
Water to 1 Litre
For use dilute 1+5
Times for thin emulsion films 7 mins @ 68oF

GENTLE agitation once per minute to preserve the 'edge effects'
