This is the E.S. Ritchie And Sons Gyro Compass Repeater, an authentic navigational tool controlled by a gyroscope, accurately indicating true north. Mounted in a bridge compartment, the gyro relays the ship’s bearing through electric cables to repeaters positioned across the bridge. This set includes an azimuth circle, fitting snugly over the compass, facilitating precise directional readings during navigation.
The azimuth circle, a straightforward instrument, enables swift and accurate bearings of celestial or terrestrial objects, functional both day and night.
Made by E.S. Ritchie & Sons from Brookline, Mass., for the SPERRY GYROSCOPE COMPANY OF BROOKLYN, NY, this extraordinary piece bears the imprints of both companies. Look for the engraved name “RITCHIE, BOSTON” on the back of the small mirror.
A remarkable addition for enthusiasts of vintage navigational equipment, this artifact is a captivating tribute to maritime history.
