Thanks Karnak, beautiful pics. How you can say the bubble canopy is ugly is beyond me.
My guide to flying spits identifies it as a Spitfire XVIIIe, owned by Rudy Frasca, based at Urbana Illinois.
The XVIII was basically the "proper" Griffon fighter, in the same way the VIII was supposed to be the "proper" 2 stage Merlin machine. The IX and the XIV were both cobbled together in haste to get the new engines in service. 300 were made. Hope it's not too long till we see one of these in AH.
