Hello Ron, I think that Alex could do worse than use your Morris as an example. I had forgotten that article in 'Army & Navy Modelworld' - I have a poor quality scan which I'll send through to Alex.
As you say, there has been debate about the colour used by 4 RNF but I think that you're correct in using red. This picture of a 50 Div sidecar at Herseaux in 1940 makes it quite obvious that the AoS background cannot be black and is the same tone as the 'TT'
