Link A-12 Sextant

The A-12 sextant was designed with Weems’ assistance just before World War II and manufactured by Ed Link, of Link trainer fame. It represented a new generation of “averaging” sextants that compensated for “Dutch roll” in airplanes by taking multiple sightings and computing an average without manual calculations.
