I bought a Nikkor P 200mm f4 lens for my Bronica S and paid very little for it as there is fungus on various elements. I am wondering if anyone has a road map to dissembling this lens, as if I could reach certain internal elements, I could probably clean the lens up quite well.

Thanks, I guess the good news is that there are only four elements. The bad news is that the retaining ring that seems to keep the front element in place just won't budge. Maybe I'll take a look at the back....
