I bought my Nikon F from a retired US Air Force fighter pilot who bought the camera new in 1964 in Japan. It has all the boxes, papers, bunch of accessories etc. The box says Nikon F Photomic, but it came with only the plain prism finder and the waist level finder. I asked him where the metered finder was, and he said that soon after he bought it he realized the metered finder was more trouble than it was worth, got rid of it, and bought the plain prism instead.
I've never used an F with a metered head (have used the F2), but particularly for the original Photomic, they're kind of hard to find in good working order, and hard to get serviced. As far as I know, my F won't work with the later T, Tn, and FTn meters without modification (which I don't want), so I've stuck with the plain prism too. It's certainly not worse than shooting with my Nikon rangefinders which are among my favorite cameras.
As for film leader retrievers, I find the little metal ones indispensable, and use one with every roll of 35mm film I develop. On the other hand, the more common plastic ones are terrible in my experience.
