Title

James Brown Monocular Microscope

Description

The brass monocular microscope has a blackened finish and stands on a claw-foot base. The foot ends in an inclination joint which allows the microscope to be angled. The coarse focus functions by a sliding mechanism with a screwed clamp to control tension on main tube. The fine focus functions by adjusting the knurled thumbscrew located at the top of the pillar. The fixed circular stage is made from glass and has an iris diaphragm with 4 apertures. The diaphragm is part of the stage, rather than the usual design of being located underneath. The sub-stage mirror is concave-convex and is set in a gimbal which allows it to be angled to catch the light. The fitted mahogany case has its original bail and lock, however, there is no key with the instrument. The interior of the case has compartments to hold the accessories and dissembled microscope.

The microscope comes with the following accessories: 2 draw tubes: 5.4" and 7.8" long (Each tube supplied with its own unmarked ocular), 2 unmarked objectives with brass canisters, 2 ocular lenses and 1 bullseye condenser with stand.

Condition:

Cosmetically: The black enamel coat beneath glass is slightly separated and coming away.
Optically: The lenses are clear and functional.
Mechanically: The free standing bulls-eye is fully adjustable and in good condition. The instrument is functional.
