Interesting .... mine is neither silver nor AI, as best as I can tell it was probably one of the last non-Ai ones. Maybe there was a version in between that was not so bad? I just acquired a Nikon AI 35-135 and just shot a roll with that and will compare results, but I confess I do still like the 43-86. I have not made any print enlargements with it, but scans hold up well when magnified to the equivalent of approx 11 x 14 or so.
