That is sweet news to see another Spit come back to life.
Incidently, the "white belly" look was in use for over a year. Officially known as Night/White Special Recognition Marking from April 1939 to June 1940.
Likely been posted before, but get a kick as this news reporter reacts to a Spitfire approaching from behind, unaware as to just how low he is flying (warning of expletives).

For my build I'm still in the midst of gluing parts. Have also discovered another detail Tamiya has missed. They omitted the gun-bay heating vents located on the outboard ends of both wings. I have two options, either to scratchbuild or cut off the vents from the wings of their Vb kit (have a resin C-wing for that model).
