Description
This copper alloy instrument is carried on trunnions on a flat tripod foot. The curved limb supports a sleeve holding the body tube. The body can be racked up and down within the sleeve, for coarse focusing, by two mill-edged knobs at the rear of the limb. The eyepiece screws into the top of the body. A vertical screw on the front of the lower end of the body moves an inner cylinder, with an internal thread to take objectives, for fine focusing. The rectangular stage has a sliding bracket to support specimens. A rotating disk with four apertures is mounted on the underside of the stage. A cylinder extends below the stage and as inner cylinder, with a pinhole to take a mirror pushes into it. The wooden case also holds an eyepiece, two Nicol prisms polarizers and two objectives that do not fit this instrument.
