So, I got my hands on another Fast Fifty last week,
It looked a bit dirty with some splotches in the front coating and what looked like fungus along the edges of the front element.
Brian did offer some advice on taking it apart for cleaning, which I promptly did. Of course, my specimen did not have the hidden set screw. I only figured that out AFTER removing the aperture ring, giving me an hour of fun reinstalling it so the numbers lined up with the dot
I managed to clean most of the internal lens surfaces, except inside the rear group (which is clean) and the center group (which is slightly dirty and for which I'd need better tools).
After reassembly I went out and tested the lens on my Leica M-E. Results look pretty good if a little glowy in the high contrast areas.
