There was also Red Baron, owned by Roy Maclain in Idaho Falls. Powerplant was a Griffon 57 driving a de Havilland contra-prop of 13ft 8in diameter, though I don't think the nacelle fairing looked as effective as the previous poster. The Griffon was taken from an Avro Shackleton developing 2,455hp for take-off and the carb intake was positioned on top of the cowling much like the earlier, Allison-engined Mustangs.
Sorry, I can't post a pic right now but you could probably google image it.
