The first Australian built Mustang assembled from parts from North American. Was one of the aircraft parked at Emu Field during the Totem atomic bomb tests in 1953. Its condition in 1967 was such that it was decided Tony Schwerdt should fly it out, first to Coober Pedy (without approval) and then on to Parafield (with approval). After failing to get A68-1 registered in Australia it was shipped to the US where it became N7773.
