Nikon Binocular viewing body for the SMZ-U stereo microscope. The Nikon product number is 83020 with a last list price of $1,150.00. This unit was a factory demonstrator so has a few small cosmetic marks where it was attached to the zoom pod, you can see these marks in the photographs. The alignment is perfect with no signs of fungus or prism separations. These heads are getting scarce to find in good condition.
