We are not sure of the actual ship this was taken from but shown are
some charts that came in with it.
Worth over $4K!The binnacle houses the main magnetic compass on a ship which is mounted in gimbals to keep it level while the vesselrocks with the motion of the water. Magnetic compasses point to magnetic north instead of the geographic North Pole.
Sometimes there was an oil lamp or, later, an electrical light source, mounted under the compass.
A brass hood sits atop the compass and has a viewing port through which you can see the direction.
The steel balls (aka quadrantal spheres or "Kelvin's balls") on either side slide to adjust the compass to compensate for the magnetic skew of the iron on the ship.
Gyro compasses are more accurate as they are based on the geographical North Pole but require electricity to work.CUSTOMER PICKUP ONLY!Note: Items sold as "Pickup only" must be accepted and signed for as "OK" at pickup time.
