Polyvar 2 Magnification Change Turret with 1x and

This is the ‘mag-changer’ turret assembly from a Reichert Polyvar 2 research microscope. Only two positions have relay lenses installed, and these are indicated on the turret as 1x and 2x. The other two positions are empty. This system may also fit the original Polyvar, but I do not know this for certain (they appear identical).
