Ed,
I can’t exactly help you with the kit but have some thoughts. I believe that the plastic for all Airfix 747’s is the same. There are a few Airfix E4 Flying White House kits on Ebay now. Maybe get that kit and a separate BA decal from someone/somewhere else? I just noticed that Airfix released the kit in 2 different versions of the BA scheme.
You also probably already know it but the Airfix 747 isn’t near as nice as the Revell release.
