Marc, it isn't a Range Rover but the last of the true Land Rovers. You can see in the picture that it has what's called a Tropical Roof, a raised roof skin above the main roof with vents on the inside that pop open to let air in form above. also vents that open just above the dash. Original AC
The color is called Limestone. A 4 cylinder diesel or petrol were the only choice until land Rover intoduced the replacement, the Defender 90, which offered a V8, The pictured is not of my actual Land Rover but it is exactly in all details what I built. All my photo's of the build are film and I've nevered bothered to scan them. When it had only 200 miles on it, my wife, son and myself drove it to Stowe Vermont ( 10 hours)to a car show called British Car Day and it took a first place. By the way all the body panels except the bulkhead( firewall) are aluminum and everything (almost) is held together using rivets.One other thing, the chassis as well as the bulkhead and the body trim as well as a lot of small parts are galvanised.
