Title
Drum Compound Microscope
Description
The drum compound microscope is made of lacquered brass. The 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 specimen platform. The body tube is moved closer or further away from the specimen platform to focus via a sliding mechanism. 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. The thumbscrew for the rotation of the mirror has the word "France" engraved in it. The fitted case is designed along a "coffin-style" that is secured with two small swing hooks. One of the hinges that holds the top is broken. The case has a small compartment to hold slides or accessories. The inside of the case has a paper plastered on it that reads: "GROSSISSEMENT. 1 lentille....30 fois.
Condition:
Cosmetically: The lacquered brass shows signs of age and use with some marks and stains. There are also signs of rust on the underside of the substage mirror.
Optically: The ocular lens is stained slightly but still is usable.
Mechanically: The microscope is functional.
