1728744839Code 8004 Aeronautical CompassSestrel H B & S London aeronautical compass made in England from the 1930s, in brass and glass, mounted on a custom-made mahogany and brass wood table. Compass diameter 13.5 cm – 5.4 inches, height with base 18 cm – 7.1 inches.
The compass is made up of a cylindrical brass container, called a mortar, on the bottom of which is fixed a hard metal stem, on which the eight-wind rose is placed, suitably constrained, so that the zero coincides with the magnetic polarity. To reduce friction to a minimum, the mortar is filled with a low freezing point liquid, which also has the purpose of quickly dampening any oscillations of the compass rose and closed by a sturdy protective glass. The compass is equipped with a graduated mobile disk inserted above the compass to set the direction to follow and which can be rotated on itself.
