London's G-HEMS was not painted red until 1997 when Branson took over sponsorship.
I have previously seen G-BLUM (in red) when Bond owned it. Thanks for the heads up on the G-BLUN I was able to locate it. G-BLUN is the one. Found it as G-AMS as used in the TV series. Apparently with special dispensation for the registry alterication.

Aerospatiale SA365N2 Dauphin II, G-BLUN, unknown
Later back again as G-BLUN after it was owned by CHC for the North Sea oil rigs (red-white-and blue color scheme) it crashed into the sea, lost all crew and passengers in 2006.
I DO appreciate the info - many thanks.
