Nikon Micro Nikkor-P 55mm f/3.5 macro lens with macro bellows and slide copying attchment. The bellows is bad in the macro rig and the slide copier. The glass on the lens has some haze. The focusing barrel truns smoothly. The aperture ring turns easily. It has been converted to ai in the old hack method of filing a notch in the aperture ring. It works but it's ugly. This can be seen in the photos.
