Title

Negretti & Zambra Compound Microscope

Description

The brass compound microscope was created by Negretti & Zambra, London. The monocular microscope is signed on the foot "Negretti & Zambra, London" as well as on the lids of the objectives. There is also a trade label at the back of the cabinet. The microscope stands on a Y-shaped base with attractive chase work to the brass below the golden lacquering. The base is mounted to a wooden platform. The main body of the microscope is supported on a single turned column that terminates in a compass-type joint. At the base of the microscope is a single sided concave mirror in a gimbal. The stage is finished again in chase work below the golden lacquer. The stage is quite simple with just a wheel of stops below and a pair of clips to the top. Focusing is via rack work to the back of a triangular sectioned bar. At the top of the bar is a simple limb held in place with a knurled wheel. The body-tube screws into the limb. The French polished mahogany cabinet has a glazed door, brass carry handle and lock with key.
The microscope includes the following accessories: 1" objective engraved "Negretti & Zambra, London." 1/4" objective engraved "Negretti & Zambra, London." 1 low power eyepiece, 1 live box, 1 slide, 1 table bulls-eye condenser and a key.

Optically: The lenses are clear with no damage.

Mechanically: The microscope is very good with no areas of wear or slack.
