This microscope's cylindrical tube moves vertically under friction inside a fixed drum for macroscopic focusing. The drum is supported on an arm extending from the cylindrical pillar, which has a screw at the end enabling the tube to be moved for microscopic focusing.

The rectangular stage is held on the front of the pillar. It has a central hole, and others for slide clips or magnifying glasses. On the underside is a disc with different-sized holes, which is used to control the light being reflected by a plano-concave mirror near the base. The mirror can be turned in various different directions. There is no tilt system.

The base is horseshoe-shaped with straight limbs that have a mechanism allowing them to be brought closer together. The manufacturer's name is engraved on the right-hand limb: "R & J. Beck Ltd. London. 21936."
