Zeiss Dumpy Level

The Ni A, Zeiss's first precise level suitable for first-order geodetic work, was produced during the years 1935-1941. This example may be one of the many instruments that American intelligence officers captured from the German geodetic office at the end of World War II. The United States National Imagery and Mapping Agency transferred it to the Smithsonian in 2000. The signature reads "Ni A CARL ZEISS JENA No. 62166."
