Got enough cash? sure you can get a spitfire built
they make them in southampton. Pretty penny though.
As for museums......
Hawkinge airfield (ring any bells?) is now a museum, it houses MANY spitfires/hurricanes/109's and memerobilia from the battle of britain.
Its extremly eery though in the fact that it also has ALOT of wrecks throughout the museum and who they belong to, and where they were stationed, how they were shot down and either taken POW or killed. Quite freaky. Would highly recommend it.
