Ex VC10
See post #9.
There can't have been a second pax door in front of the wing as the only VC10s available for filming are three Super VC10s, all with second doors behind the wing. Unless they used XR808 at Cosford which is very unlikely as that meant that they would also have to lengthen the fuselage using the computer.
G-ASGC is the most likely answer as that is the only one that has the nose gear doors drooping open, something clearly visible in the screen shots from the series.
