RX163 is supposedly at Duxford; according to Geoff Goodall's site the remains included the wings and some fuselage parts. Initial rebuild was by Steve Atkin and Chris Warrilow with a new build fuselage (from Airframe Assemblies?) before moving on.
I went to an excellent airshow at Baldonnel in the mid-80s, most of the IAC fleet seemed to take part; I recall they had Fouga Magisters and SF-260Ws for advanced training and also a light attack role?
