Thanks to everyone for the reply.
My modelling project should be strictly wartime thimble nosed, fin fillet Beau TFX with white SEAC bands, however, it seems, all what we have so far, is this single photo, which doesn’t unfortunately provide enough info for the correct representation on a model…
Anyway, trying to summarize this really interesting discussion:
- the colour and location of the s/n as depicted on the profile can probably be confirmed;
- the lack of the code letter on the operational a/c is possible;
- the first 2 digits of the serial are most likely "RD" and the rest is probably not "747";
- all other known pictures show either post-war or ferry a/c or the ones without SEAC white bands.
As for the camo TLS vs. TSS: as said, the caption to the same photo in some old issue of “Scale Aircraft Modelling” does suggest the Temperate Sea Scheme. However, the serials on the RD770 or RD 758 SNAKE (I also have the photos of them) reported to be painted in TSS are located under the horizontal tail, while an alternative location could suggest repainting.
The only hope could still be some unpublished photos or other material. Otherwise, the only alternative for the wartime late TF X is the Coastal Extra Dark Sea Grey over Sky without any other decoration. Too bad as I really like the SEAC roundels and white bands...
