Seek and ye shall find, indeed. Thanks DF and PE and everyone else. I remember using Edwal 12 some years ago and at the time I thought it was a bit relentless of a developer. The main reason I'm interested in Edwal 10 is to see what effect the glycin has. I'll still make up some Agfa 8 so I can see glycin "unsullied" by metol, but for now I'll try the E-10, and report back.
