Nice stuff there Vic. However, I'd be vaery wary of the profile showing the red code letters, and I've already mentioned this to Jan.
Although there is a slim possibility that red codes might have been carried at one time, it's doubtful. This is something that has persisted sind the 1960's, with kits, decal sheets and profiles showing the red squadron codes, a yellow individual code letter, and, in some instances, a yellow spinner. The original codes were the standard Sky examples. When the AEAF stripes were painted around the fuselage on the evening of 5th June '44, the 'TP' squadron codes were covered, and smaller white characters were painted on the fin, with the individual code letter repeated on the nose, either near the camera gun port, or above the exhausts. The fuselage code letter remained, in Sky. Some aircraft also had the individual letter, in even smaller characters, alongside the squadron code on the fin.
When the upper fuselage and wing stripes were removed, in early July '44, the 'damaged' squadron codes were re-painted in Medium Sea Grey, probably because this (light) colour was more readily available in the field than Sky. Comparison of the tonal values of the codes, in B&W pictures with that of the red of the roundel and fin flash, show that there isn't even a near match, and that the tone of the codes does match the tone of the underside colour.
Hope this clarifies things !
