During the first rollout of the VC10 prototype G-ARTA, it was photographed from a helicopter, a Westland Widgeon. I have found a photo from the Sunday Express that shows this helicopter, see below. Would anyone be able to help me with identifying this particular Widgeon? I have a sneaking suspicion that it might be G-APPS, used by Bristow Helicopters, but I would appreciate a confirmation or any additional information.
I found this image of G-APPS, and while the colourscheme is pretty close, I wonder if Bristow had other Widgeons or whether there was another Widgeon with a comparable scheme operating in 1962:
