To yazman's IAS fleet list must be added Rapide G-AGUF — perhaps the best known of their Rapides. I flew in it as a child from 'London Airport' as we called it then with the redoubtable 'Aggy' Agazarian. Can't recall exactly when, but I think there were BOAC Comet 1s around so probably 1953. More than a quarter century later I met 'Aggy' again when she was running a simulator operation at Booker.
Ah, I see now that Treadders' model is of that very same aeroplane...nice!
