Just popped up in my head this morning (that's what happen when you wake up early and you flick through your books), RAF P-38 Lightning fitted with XX Merlins and Vokes Tropical filter....
That is, if RAF had gone through with their 600+ P-38 order and worked with it....
First of all, would the XX Merlin fit inside the E, F, G and H models?
That Vokes can maybe be massaged to fit...
The Lightning would look interesting with a Vokes tropical filter and RAF desert colours...
D*mn you, you overactive imagination and early mornings.....must be the boo....coffee or tea me thinks!
Another thing, of course the superchargers would have been mounted back on again!
