Brief Description: This large copper alloy binocular microscope stands on a flat tripod foot on a wooden board. The base has wooden fittings, faced with black cloth for accessories. The heavy limb is supported on trunnions with a locking lever. Two mill-edged knobs operate a rack and pinion that extends a square bar from the limb. The arm supporting the body is attached to the top of the bar. The binocular body tubes screw into the top of the arm. The nosepiece, holding a prism, is mounted below. There are three objective lenses on the instrument, which can be used in combination, that screw onto the nose. Blackened eyecups push over the eyepieces and two knobs at the top of the body adjust the inter-ocular distance by racking the eyepieces in or out of the angled body tubes. A bracket on the limb carries the mechanical stage. The stage plate is rectangular with a rectangular stage hole. Two knobs move the plate back and forth and from side to side. This mechanism is attached to a copper alloy ring and a third knob, extending vertically below the stage rotates the whole assembly. An adjustable mounting for a condenser and a plano-concave mirror are set below the stage. A copper alloy tube assembly, a single objective and a mahogany box of glass slides are present with this microscope.
