Provenance Back-up station barometer from Delta's headquarters and airport operations at Selman Field in Monroe, Lousiana, that was mounted to back of building. The System Paulin barometer is a type that was commonly used by airports as station barometers.

Salvaged by Delta employee Fred Pharo, who visited the abandoned building in late 1950s/early 1960s. He found little of note except this barometer, which he unscrewed from back of building, took home and mounted it in his ham radio (amateur radio) shack at home in East Point, Georgia.

Fred Pharo was hired by Delta in 1938, and retired after over 50 years as Director of Communications in Atlanta. The barometer later passed to his nephew Mark Pharo, who donated it to the Delta Flight Museum in 2013.

Mark recalls "Uncle Fred stated that the main station barometer was mounted in communications (I believe on the right side of building as you were facing it), the backup was mounted on the rear of the building as best as I recall. He said that whoever was working as the radio operator would have to note the barometric pressure several times a day and that the pilots would check it prior to take off. This barometer was the backup/redundant system." Source: E-mail from Mark Pharo to Delta Flight Museum Director - Archives Marie Force, 7/10/2013.
