There was a complete Comet 1 fuselage at Farnborough up until the early '80s. Part of the mothballing had peeled away revealing Air France markings. Can't remember if it had square or round windows. I'm not sure what happened to it but last time I saw it was near the airfield fire service practice ground.(not the present one, this one was on the north side in what is now Qinetiq), previously it had been in 'the dump' on the north side and prior to that near the test tank on the south side.
