It works very well this way, Mike - nicely done.
I think the Spit outside RAF Turnhouse was genuine - I'm talking about the '60s and early '70s when I used to see it. When the whole place was modernised / upgraded / redeveloped, the Spitfire disappeared, perhaps to be refurbished and to fly again - who knows?
Later.
The Spitfire I remember was genuine - serial RW393, 603 Squadron. When the airfield was redeveloped it was replaced with a generic GRP 1:1 replica. The original is believed to be in an air museum somewhere in the Midlands.
