Antique Compass – signed Jos. Schablass & Sohn, Vienna, ca. mid-19th century
A truly exceptional 19th-century measuring instrument, crafted by the renowned Viennese precision engineering workshop Jos. Schablass & Sohn.
The instrument is mounted on a solid, square brass plate with factory-drilled mounting holes. The central part of the instrument is occupied by a glass-covered, round compass housing.
The dial bears the manufacturer’s name: “Jos. Schablass & Sohn in Wien” and the serial number “N. 56”—a low number .
The dial also marks the four cardinal directions (N, S, E, W—with the traditional reversal of east and west found in old compasses to facilitate direct reading) and a precise degree scale (0°–360°). The instrument is equipped with an original, slender steel magnetic needle with a brass counterweight and a side-mounted needle-locking mechanism (known as an “aretage”).
Josef Schablass (1793–1870) was one of the most highly regarded Viennese mechanics and makers of mathematical, optical, and geodetic instruments during the Austrian Empire. After his son joined the company, the firm began signing its products as Jos. Schablass & Sohn, supplying precision instruments for mining, railroads, and the military.
The products from this workshop are characterized by excellent craftsmanship and are rare on the antique market.
Very good condition, patina.
Dimensions: 15.5 x 15.5 [cm]
