Title

Dollond Cuff-Type Microscope

Description

The cuff-style compound microscope is made from brass and is secured to a square mahogany base. The single-sided plano-concave mirror is mounted on a gimbal and connected to a brass mounting on the base which can rotate. The Bonnani stage is signed "Dollond London" and has a small removable bullseye condenser attachment. Beneath the stage are two stage clips which hold the specimen in place. The instrument comes with a removable spring-loaded attachment which slots into the circular cut out and acts as a method to hold a specimen in place. The stage is supported by a rectangular pillar, which is parallel to another movable pillar for coarse focusing. The movable pillar slides up and down, adjusting the body tube relative to the stage. The focusing is controlled by a Hevelius screw, with the top mount fixing the body tube in position, and the screw thread adjusts the position of the body tube along the pillar. The pillar has numbered markings which represent the position of the body tube from 1 to 6. The body tube sits in the arm attachment at the top of the pillar. The eye piece has a sliding brass protector. The instrument is housed in a pyramid-shaped mahogany case with an interior draw in the base. The case has a brass carrying handle and is secured by a lock, however, the key is not present with the instrument.

The microscope comes with the following accessories: 2 test tubes, 2 keys, stage bullseye condenser, glass disk, collection of dead insects, thin wire, 1 fish plate, 6 projection lenses (for solar microscope), 6 objectives (stamped 1-6), 2 dovetail slides, brass container, brass stage attachment and 1 spring-loaded stage attachment.

Condition:

Cosmetically: The brass has darks marks from age and use. The substage mirror is in good condition.
