1730995081Code 8031c Magnetic Bearing CompassHand-held magnetic bearing compass, signed Henry Browne & Son Ltd Sestrel Made in England, N. 6162/B Barking & London from the early 1900s.

This is a small antique compass, made of brass with a wooden handle typically used in recreational sailing. It is equipped with an optical prism aiming system to magnify the degrees placed on the graduated eight-wind rose so as to make it possible to measure the angle between the aiming line and the north indicated by the magnetic needle. The compass is made up of a cylindrical brass container, called a mortar, on the bottom of which is fixed a hard metal stem, called a sensitive element, on which the wind rose is placed, suitably fastened, so that the zero coincides with the magnetic polarity. To reduce friction to a minimum, the mortar was filled with a low freezing point liquid, also having the aim of quickly dampening any oscillations of the complex and closed at the top by a sturdy protective glass and complete with a wooden handle.
Sestrel is a registered trademark of Henry Browne & son, which was an important English company producing high quality compasses, inclinometers, sextants, etc. founded in the second half of the 19th century. The brand is a name that results from the initials of the qualities that the brand itself embodies: SEnsitive – STeady – RELiable (sensitive-safe-reliable). Sestrel is in fact a name synonymous with quality and precision, as demonstrated by the number of vintage and antique instruments with that brand still in use today.
The invention of the compass is surrounded by a legendary halo. However, it is known that the discovery of magnetite, a material capable of attracting iron, occurred in Magnesia, a city in Asia Minor from which this stone takes its name. The first hints of the use in Europe of scientific instruments that exploited magnetic force to orient oneself in navigation date back to the end of the 12th century, above all thanks to the knowledge brought by Arab merchants and navigators.
