Brief Description: The brass instrument stands on a plate, with a shaped supporting strut, on a box base. The pillar consists of two bars held together with brackets, standing in a boss. The front bar is static and holds the stage. The rear bar holds an arm supporting the body and can be moved up and down by a vertical screw for focusing. The body rests in a brass ring. The upper section has eyepiece and field lenses and a blackened eyecup with a sliding dust cover. The narrower lower tube has an external thread to take objectives. The cruciform stage is inscribed with the maker's name and has a keyhole slot and a spring fitting for accessories. A concave mirror is mounted on a disk at the centre of the top of the base, which is mahogany and has a drawer for accessories. The drawer contains six objectives, a cone condenser, stage forceps on a steel pin, a Lieberkuhn in a can, a Lieberkuhn carrier, a glass stage disk, an ebony slider with no specimens, a fishplate and a circular spring stage that pushes into the stage hole. The pyramidal case is mahogany.
