Title

Charles Baker "Ross Type" Microscope

Description

The Charles Baker compound microscope comes with the original mahogany case. The brass microscope can be dissembled to fit into the case. The body tube and arm are secured via a thumbscrew to the mahogany platform which is fixed to the claw-footed base of the microscope. The lacquered brass foot has "BAKER, 244 High Holborn, LONDON" carved into it. The body tube and arm can then be attached via a screw to the pillar of the microscope. The fixed square stage is attached to the pillar and has a square fixture that can be horizontal to adjust the specimen. There is a substage revolving diaphragms that can be removed via a sliding mechanism. Coarse focusing functions via a rack and pinion mechanism and fine focusing is operated via thumbscrew found on the arm. The substage, one-sided mirror is permanently attached to the pillar of the microscope via a gimbal. The mahogany case is farcened with a brass lock which is no longer present on the case with the escutcheon missing. The wooden fitting that would originally have held the two objectives in the case is half missing and so the accessories are now being held in the draw located at the bottom of the case. The draw has a brass pull loop to open and close it. The case also has a brass handle at the top that is used to carry the case.
The microscope comes with the following accessories: 1 nosepiece analyzer, 1 live box, 2 substage sliders: 1 holding a rotating disc of apertures, 1 rotating polarizer, 2 objectives: 1 signed by A & B Franks of Manchester, the other is unsigned.
