A cone diaphragm is fitted on the underside of the stage and a concave mirror is held on a pivoting mount near the base of the pillar. The body tube is held in a brass ring on an arm attached to the top of the pillar.

Accessories include eight sliders, six objectives, a lieberkuhn in a can, a lieberkuhn carrier, a glass phial a live box and a fish-plate.
