What type of range figures do you want?
Still air cruising, ferry range or combat radius? All three are quire different.
Range depends markedly on speed and altitude flown.
The problem also exists in that even in the same aircraft type, there were many different ranges, due to differing configurations and internal fuel carried.
Supermarine Spitfires had best cruising speed ranges on internal fuel of between 430 and 840 miles. Even individual sub-types had differences: some Mk IXs had 85 Imp gal internal fuel, while others had 94 imp gal (or about 10% more fuel). Vary late war Mk IXs were also fitted with a 45 imp gal rear fuel tank.
Same can be said for the Tempest V. There was an optional front nose tank, 20 Imp gal IIRC, which added about 15% to range.
