I remember seeing Freddie Laker's Rolls-Royce on the scissor-lift at Southend, it too was being loaded onto a Carvair, I don't know if it was just for a publicity photo or if he was taking it somewhere because I had to leave before they closed the doors, but I expect if it WAS for the latter, that he'd have got a good deal on the fare!!
Also at Southend, you could often see the short nosed Mk31 Bristol Freighter/Wayfarers operated by Channel Airways and Sabena.
