Compound microscope

The body of this microscope has a cylindrical tube with the eyepiece and lens at the ends. The tube is attached to the back pillar with a rack mechanism controlled by 2 side screws for coarse focusing. Fine focusing is achieved by rotating a screw on the back of the stage. The pillar bears the manufacturer's inscription: "Smith & Beck, 6 Coleman St. London 943." The rectangular stage sits on the base. It has a large central hole to let light through and another hole for the slide holder. Lower on the pillar is the plano-concave mirror, which moves freely. It has a joint between the base and the pillar with a screw to tilt the microscope until it is completely horizontal. This is made easier by the weight of the base, which has tripod legs that fold away under the cuboid base.
