Mike:
Thanks for the timely response. Neither misprint nor miss print, whoever she may be, it is. An
'f = 50mm ~ f = 300mm ... Zoom NIKKOR Auto 1:4.5', carrying
No.757232 is engraved below the cap. It has been used very little, and been waiting for a serious hobbyist's Nikon SLR to drop into an appropriate price range before mating the two. I had my mind made up for a D5500, but I'll check out the 7xxx per suggestion.
My lens is similar to yours in the picture, except the knurling on the zoom and focus rings is dissimilar. As the "No." (s/n) is not shown on your picture, it's difficult to know the lot to which it belongs. Major internal changes supposedly occurred at lens
Nos. 740101 and
750101[SUP](1)[/SUP]for the 50-300, but I don't know any specifics.
