Solid brass round Box Sextant, made in 1803 by instrument maker William Jones in London. Meant for terrestrial observation, also suitable for small ships. French sailor Jean Lancombe used a Box Sextant for his single-handed Atlantic crossing. The heavy brass Box Sextant measures 3 inches (7.7 cm) in diameter and weighs just over a pound. The instrument has a brass cover that unthreads and rethreads onto the opposite side where it functions as a holder. The sextant's thickness is only 1 5/8 inches (4 cm) with the cover installed. When the cover is removed, the telescope is extended and the larger knurled knob can be adjusted to align the images. The magnifier assists in reading the inclination angle from a precision German Silver vernier scale. The small knurled knob unscrews for use as a tool to adjust the horizon mirror. The sextant also includes a removable moon filter.
