You get a Nikon F Mount PRE AI Compensating Micro Nikkor 55mm f/3.5. Serial number 191966.  This dates from 1964. The lens has a clean diaphragm. The glass looks quite nice. No fungus, haze or scratches. I will include a Nikon M 1:1 Macro Ring and a L1A filter. Generic caps are included. 

The lens has no dents. The scalloped focus ring shows obvious wear and there are some edge nicks. The main issue is the focus is no longer smooth throughout the focus range. It does fully work, but it tightens up in a couple of areas.  

Overall condition very average with nice glass. The lens is 60 years old and still very useable. 

Free USA shipping. All other buyers pay actual shipping costs. Regards, Darryl
