The lens was designed and released with the Nikon I. Initially it was of heavy chrome over brass construction, lacked click stops on the aperture and only stopped down to f/16. The first batch of serial numbers was 801xxx. These lenses were marked MIOJ on the side of the lens barrel. Later batches were marked on the rangefinder cam.
The next batch ran from 9031 through 90489, followed by a another batch from 268500 and run through 296xxx. At around number 287300 the MIOJ markings were replaced on the rangrfinder cam with "made In Japan". Then at around 289xxx "Tokyo" on the beauty ring changes to "Japan". Here generally the lenses acquire clickstops and stop down to f/32.
Serial numbers jump to 3967xx and run through 404xxx, then jump 496xxx through 497xxx, this last batch finished in black.
Like most Nikkor lenses offered early, they lose weight gradually over the years. Shades progress from heavy chrome over brass slip on, to alloy screw in, to black clip on. The lens takes 48mm filters and caps.
