And here's G-FIRE at Palm Springs:
I was there on Christmas Eve and very surprised to see a Spitfire XIV in the museum. I didn't realize it was G-FIRE.
treaders,
You are right about the camouflage - it's definitely blue rather than grey and the green is the wrong shade as well. Also the fin flash doesn't match the roundel style.
BTW, it's a great museum. A must see if you are in the area.
