Title

Round Base Compound Microscope

Description

The compound microscope is made from lacquered brass and stands on a weighted circular base. The cylinder pillar screws into base and is connected to the stage and body-tube. The microscope can be disassembled in order to fit into the original case. The instrument has a square fixed with stage clip attachments to hold the specimen in place. The stage is spring-loaded and the lower section is painted black. The sub-stage mirror is connected to the lower section of the pillar and is set in a gimbal which allows it to be revolved. The body-tube screws into an arm extension attached to the top of the pillar. Coarse focusing functions by rack work controlled by a thumbscrew at the side of the pillar. The microscope focuses by moving the body-tube closer or further from the stage. The case has wooden compartments to hold the dissembled parts of the instrument and the lid is lined with red velvet. The case is secured by a lock and key which is not present with the microscope.

The microscope comes with the following accessories: brass forceps, 2 objective lenses, brass canister for mica disk slide covers and brass tray with glass bottom.

Condition:

Cosmetically: The brass still retains some of its lacquer but has marks from age and wear. The sub-stage mirror is in good condition.

Optically: The lenses are clear and functional.

Mechanically. The coarse focusing rack work does not always work but the instrument is functional.
