That seems like a very reasonable assumption Albert, even now, looking back after so many years have passed. I must admit though I don’t know how much commonality existed with the various panels of the T and AS variants,certainly the bulge below the cockpits on the trainers was larger and more pronounced, but apart from that rather obvious difference many other parts/panels would have been interchangeable. Wonder if the inside of the different panels would have been stencilled at some stage in their service life with the aircraft serial and could thus solve the mystery? Would that be a possible task perhaps from someone nearer the present location of XA308? or maybe even a written request to the right source? [Am thoroughly enjoying this, but must sign off tonight.(I’ll probably drift off hearing of the bumble-bee drone of Mambas in full song in my head! (with any luck!)] I’ll look again in the morning.
