|Brief Description:||This brass instrument has a limb, carried on trunions on a tripod. Two double mill edged knobs on the rear of the rectangular limb extend a bar, with a dovetail cross section, supporting the optical components. A binocular or monocular body can be screwed onto an arm, inscribed with the maker's name. Objectives screw into a cylinder on the underside of the arm. A graduated screw on the arm moves the cylinder for fine focusing. The stage is mechanical and the stage plate has a sliding, sprung bracket to hold specimens. A mechanical mounting for a condenser is set on a plate that can be racked up and down below the stage. A sleeve on the cylindrical lower end of the limb holds the plano- concave mirror on an articulated arm. The mahogany case contains a box of accessories including two monocular body tubes, a binocular body, eight objectives, four eyepieces, two substage assemblies with a choice of apertures, an achromatic condenser, and a number of prisms and camera lucida.|
