Description

A Cuff-type microscope, possibly German, late 18th

 An hitherto unrecorded compound microscope, unsigned, possibly of German origin.

Last quarter of 18^th century.

 Dimension: 14 5/8” (37cm) high overall, mounted in the top of the 6 ½” x 8 ¼” x 3 ¼” (15x21x8cm) fitted mahogany case.

The body tube is 5 7/8” (14.5cm) long x 1 ¾” (4.5cm) diameter and screws into an arm at the top of the pillar; coarse and fine focussing is by a Cuff-type mechanism (sliding block with a clamp screw and long threaded screw connecting the block and the arm holding the body tube) and the 2 ¼” ( 6cm) diam. single-sided mirror (mirror glass modern, brass frame original) is mounted in a plate at the base of the pillar.

Accessories comprise a Bonanni-type spring stage to be screwed into the stage, a small stage mounted bull’s eye condensing lens on articulated arm and one wooden slide (# 4).

The inside of the drawer is covered with 18^th century printed paper that recalls German manufacture.

A very rare compound microscope, only another one very similar in a French private coll.

Despite some signs of use, few functional small repairs and the absence of a dust cover, a still handsome and rare model.

A comparison can be made with #132 of the Golub Microscope Coll.
