The Griffon-Spitfire on this proud Vickers-Armstrongs poster reminds me a Sept. 1942 photo of the F Mk. IV prototype (DP845) which became the Mk XII prototype.
S-uperlative.

Aviation Rapture 
Are you sure it is a MK XII? This one has the elliptical wings. I believe, all XIIs had clipped wings.
The prototype had the classic elliptical wings.
Both Elliptical….
… and Clipped.
I forgot about the prototype.
For your listing enjoyment, I give you the mighty Griffin! https://www.youtube.com/watch?v=8POTLnXuS_I
That supercharger’s whistling touch….
When I was young, I hatted the clipped wing Spitfires, now I find I like them better!
Same thing has happened to me.
