Description
POLISH FOUR-VANE SURVEYING COMPASS, c. second half 19th century, finely signed on the silvered compass face “G. Gerlach w. Warszawie No. 84.” Measuring 16″ (41 cm) overall, this fine solidly made brass surveying compass has two folding vanes and two fixed vanes which mount from underneath. It is complete with the original carrying case and a large brass pin, but lacks the universal staff mount. Condition is very fine noting only a few spots to the original clear lacquer finish. The Gerlach firm was in business from 1816 to 1944. An 1884 catalogue proclaims G. Gerlach as the “Only Russian manufacturer of geodesic, mathematical, drawing and optical instruments,” and lists his factory at 30 Tamka St. (his home) and the store at 2 Tchistaya St., Warsaw. (Warsaw was, of course, part of Russian Poland under the tzars at the time). A rare and very fine example of a Polish instrument. (8265) $4950.
