VH-AUB is a CAC CA-18 Mk21 Mustang, which was registered A68-107 to the RAAF in 1947 and served for 11 years. It was painted red after 1958, and was rarely flown until it was dismantled in 1966 and transported to an outback station in Queensland. In 1978 VH-AUB was acquired by Col Pay and became his pride and joy. Restoration began and the aircraft was repainted to its original RAAF colour scheme. VH-AUB remains a prized possession in the Pay’s warbird fleet based at Scone, NSW, Australia.
