Benjamin Martin attr. Universal Microscope

A Universal Microscope unsigned but attributed to Benjamin Martin (1704-1784)

London circa 1770

made of lacquered brass, folding tripod, concave-mirror in a gimbal (gimbal with old repair),

stage, fine focus mechanism.

Condition: seems almost perfect. The dark color of the brass lacquer and the darkened brass parts (feet) seem unusual compared to other Benjamin Martin microscopes, so it could be that the lacquer was renewed circa 1900.

Height c. 33,5 cm.

Provenance: German private collection since circa 2005, then Austrian private collection.
