Robby's Aircraft became Robby's Aerial Services and this Tiger Moth became VH-RAO in 1952. It was based at Parafield aerodrome, Adelaide. There looks to be runway markers in the background while the disposition of the runway fits the layout of Parafield. The hills match the general topography of the area around the airport but it is not 100% certain this is YPPF.
