This is an early period Nikon F lens - a Nikon Nikkor 135mm f/3.5 Auto NIKKOR "Nippon Kogaku" Pre-AI Lens
Overall condition is very good - please see images attached.
The lens optics are clean, nothing to affect picture quality. Light haze at the very edge of the outside area of the lens elements, hard to see and NO effect on anything.
Although this is now a 55-60 year old lens it will produce images NO different to the day when it was sold NEW.
Focus and aperture movements are good, no issues.
Great to match with any Nikon or Nikkormat from the period.
