Just out of interest, a couple of weeks ago, I was driving up to see a pal who lives north of Grantham, just off the A1, when, just before the service roundabout north of Grantham, travelling south was a Comet front fuselage mounted on an artic, painted grey and with an RAF roundel painted on the cut off rear, it seemed to be an RAF promotion vehicle/a/c, anyone have any info on it. Sorry to interfere with your excellent Royal Comet thread, I thought it may be the same one though, just a chance, who knows.
It sounds like the Comet fuselage that’s mocked up to look like a Nimrod and used for RAF recruiting. It used to be in ‘hemp’ colour. so maybe they have repainted it to look like the latest Nimrod scheme?
