Gyroscopic Sextant


Sextant made for the German navy and probably used during World War II. An instruction label in the box is dated "Januar 1945." The inscription on the instrument reads "J. B. G Gepr├╝ft Deutsche Seewarte." Like the SOLD sextant made by Plath, this one has a gyroscopic artificial horizon, and an integrator attachment that averages several observations taken in quick succession. The Smithsonian purchased this example from Laboratorium Dr. Justus Rosenhagen, a scientific instrument maker in Hamburg who had assembled a collection of historic instruments.
