Thanks for the kind comments Kev.
Danny,
I am not sure on the colour, I researched it at the time and I think it is correct?
I researched it at the time and came up with this:
Three Talbots were entered in the 1926 British Grand prix held at Brooklands
they were painted in the colour of British racing green rather than the usual
blue.
Information from 'British grand Prix' by Richard Hough
I hope that explains.
Kind regards
Eric
