If the Red Pelicans finished in 1973, probably the last team was:
Sqn Ldr I.C. Gibbs, Capt R.F. Lord USAF, Flt Lt W.B. Byron RAAF and Lt J.M. Edwards RN (sadly no longer with us). I only know because I still treasure one of their brochures to remember my one and only JP flight with Marcus Edwards in October 73.
