Mine is in the second round made between 71-73. I got lucky with mine, already AI converted. Glad I didn't have to take my copy apart. It focuses a little gritty from time to time, but the rest of the lens is in great shape mechanically. Front element has a few scratches on it, but nothing that affects performance.
My focus action is pretty smooth all around, only the hood is a little sticky. I don't even remember when and where I bought it, but it had to be back in 1988 on my first John Muir Trail hike. Today I'd think twice about carrying a lens this heavy for 220 miles, but there were no plastic VR G type zooms available at the time.
Image quality is great, except for the typical fringing for the lenses of that period. Purple and green, both very visible at f/2.8 and even f/4, but ARC does remove most of it very easily. Software these days gives these lenses another lease on life.
