Theodolite - « E

Superb antique brass theodolite/surveyor's square with integrated compass, broken, cracked, dating from the late 19th century or the very early 20th century (around 1880–1900). “E. Malacrida – Optician – Marseille” This surveying instrument was used by surveyors and engineers to draw or check right angles in the field, before the widespread use of modern optical theodolites. The cylindrical body features several 90° sighting slots and a circular scale engraved at its base. The upper part is hinged, allowing precise adjustment of the sighting direction. Entirely made of solid brass, the instrument shows a beautiful patina of age, testimony to its age and the quality of its craftsmanship. A fine old scientific instrument, both functional and decorative, perfect for a collector or amateur of engineering objects.
