I found along some old books from my grandfather a lot of marks, etc, about a developing formula - the PAC´s "New Winchester". I would like to test this developer, because the blacks he used to get are very very difficult to obtain (I ever tought that the papers he used were the responsible, but maybe...)
The problem is that the formula uses two ingredients that I don't know. "Wettol" and "Latitol U". Wettol is a wetting agent, and I can try with any other. But how about Latitol? It would be like benzotriazole (Kodak Anti-fog 1), if I understood well. But then, how much of it?
Of course these are names, products, etc, from the 40s and 50s; but I really would like to try this.
Regards,
Martin
