Commonwealth Aircraft Corporation built Mustang with the Royal Australian Air Force as A68-187 from 1950 - 58. Several owners had Australian registrations reserved for the fighter, but none were applied. It was converted to Rolls-Royce Dart power and ground run, but not flown between 1971 - 77. The Merlin engine was re-installed and it was stored until exported to the USA as N919WJ for World Jet, Inc in 1995. The Warbird has been flying again as N50FS since conversion to a TF-51D using parts from P-51 44-74839 (cn 122-41379) in 1996.
