Fauth Theodolite

<< >>
G. N. Saegmuller described this as a "Four inch Theodolite, As furnished to the U. S. Government Surveys," and priced it at $300. This example was made after 1887 when Saegmuller began putting serial numbers on Fauth instruments, and before 1905 when Fauth & Co. went out of business. The U. S. Coast and Geodetic Survey transferred it to the Smithsonian in 1929. The horizontal and vertical circles are silvered, and read, with opposite verniers and magnifiers, to 30 seconds. The signature reads "FAUTH & CO. WASHN D.C. No 966" and "U.S.C.&G.S. No. 160."
