Nikon Mitutoyo x'y' measuring stage. This stage will fit the Nikon Labophot and Optiphot 1 and 2 versions.  It will also fit the Nikon Microphot microscope.  It has two Mitutoyo digital vernier measuring calipers.  It has the ability to zero and measure in both English and metric standards.  Both measuring calipers can output via an interface cable.  Only one cable is included.  Both of the #.357 batteries have been replaced and the measuring scales are functioning perfectly.  The condition of all components is nearly mint.  This is a very rare stage that has had recent service.
