The Genairco aircraft registered VH-UOG was built by the General Aircraft Company at Mascot and registered in Sydney in June 1930. The design of the Genairco was based on the popular English-designed and built DeHavilland Moth but using the wing design of the English Avro Avian.

VH-UOG was the trial aircraft for the installation of the Harkness Hornet aircraft engine, designed by Sydney automotive engineer Donald Harkness and manufactured at his works at Drummoyne.

In October 1935 it came into the ownership of Dr T J Henry, father of Goya Henry. The younger Henry had a disregard for regulations and in 1936 he was advised that his pilot's licence was suspended because of various breaches of the Air Navigation Regulations. Several days after the suspension of his pilot's licence he flew the Genairco, named by him "Jolly Roger", under Sydney Harbour Bridge, being the first pilot to do so and in contravention of the law.

The Genairco was placed in Goya Henry's name in 1940 and it was sold to Macquarie Grove Flying School in 1946. After passing into the hands of a succession of owners, including Airworld at Wangaratta in 1985, the Genairco was purchased by the Museum in 2007.
