Up for sale is a used, manual focus Nikon / Nikkor 135mm f/3.5 AI-mount tele prime lens, serial #249737, which features a built-in telescoping hood and comes with both caps.  The glass is in clean shape with no scratches or fungus present.  As with all older lenses, there are some tiny specks of internal dust, but this won't have an effect on image quality.  Focusing is smooth, with close focus down to 4.3 feet; the diaphragm is likewise functioning smoothly and there is no oil on the aperture blades.  Cosmetically, there is moderate overall wear to the barrel from age and previous use, particularly to the hood which is scratched and scuffed.  Please be sure to fully enlarge the provided photos, and feel free to contact me with any questions you may have.
