ha ha, it is funny to see this old thread.
Since posting the thread, I sold my mint NK F and the black Apollo.
Then I had a bout of sellers regret, and re-bought a black NK F (with a minor dent due to the Photomic meter) and a not-mint chrome Apollo.
But, also acquired a mint black Nikon F. So, I went from 2 F's, to zero and now three.
Such is the way with F ownership.
