Hi All,
Thank you for all your suggestions and encouragement, as for the size and placement of the fuselage insignia there are all sorts of variation from available archive photos, whether its based on air groups, periods, theathers and rebuilt vintage airframes.
To be more precise and build to look more like the original I think I'll have to look up a particular aircraft and obtain it's photographs as the sole reference, then nothing can go wrong with that, I think !
In the meantime, here's another close-up of the TBF, this time the engine cowling, hope you enjoy the built so far,

Cheers,
Hermann
