I bought this Fed 2 with an Industar 26M lens from Ukraine. Went through the usual CLA process at home and polished the aluminum beading, after removing the black paint. It was peeling off anyway. This model is a bit unusual; it has a beading that wraps around the lens mount much like the Zorki C, 2C and 6. Other models of Fed 2 do not have this broad a beading either. It is also rare and I think it is one of the later models before they changed to Fed 3, which has a similar bead. I have seen this before only with JDM in his Red Fed 2. I modified my brew after extensive readings of Anschell's Film Development Cook Book and other similar write ups. I increased the Boric Acid and salt [NaCl] content in the brew. I am told that Boric Acid "buffers" the developer meaning that it keeps the pH value constant. How ? I don't know; funnily no body is explaining it either, whether it is Anschell or Gearge Eaton fo Kodak or others. Possibly these are arrived at through empirical experiments. The salt is said to be a restrainer and should give a finer grain, more uniform [a la Microdol-X]. Again, that is not really explained well except for the speculation that it was discovered during WWII by photographers on the field, when they were forced to use sea water when there was a shortage of fresh water. Others feel that it could be acting just like Potassium Bromide, the traditional restrainer. So I tried these things with some success more like an Alchemist mixing different brews hoping to "extract gold from Tiger's urine!" Here are some results.
