Title

Drum Compound Microscope

Description

The drum compound is made of lacquered brass. This style was manufactured in France, Germany and England and sold throughout the United States and Europe. Many of the microscopes manufactured using this design were unsigned due to the huge quantities sold by various makers. The microscope consists of a body tube suspended by a tubular base above a circular specimen platform. Coarse focusing is achieved via a sliding mechanism in which the body tube is moved closer or further away from the specimen platform. A bullseye condenser is attached to the front of the microscope which can be adjusted via the double-jointed arm. There is also a concave substage mirror located in the bottom of the microscope, which can be seen through a square cut out. The mirror can be adjusted by thumbscrews on either side of the microscope, however, the mirror is detached on one side. The "coffin-style" wooden case has compartment for the microscope and slides. The case is secured with two swing hooks.

The microscope comes with the following accessories: 2 objectives; 2 slides of minerals from the Michigan Mining School (dated c.1885-1897) 3 slides prepared by W. Harold Tomlinson.

Condition:

Cosmetically: The lacquer has stains due to use and age.

Optically: The ocular is slightly marked which restricts light.

Mechanically: The microscope is functional. The mirror is not attached on one side so needs some maneuvering to catch light.
