Thanks Denny, it's a Brooklands and the color is (guess) Brooklands Green or Bottle Green. Not exclusively RR, Jaguar and other British makes featured this color.
It was one of the Limited Editions in '92 to boast more sales of the RR.
It started in '90 with the CSK, the last two-door as an hommage to chief designer Charles Spencer King, featured in Beluga Black with chrome bumpers and 5-spoke TWR wheels (Tom Walkingshaw Racing, only 200 build).
Prior to the introduction of the LSE (108 inch wheelbase instead of 100 inch) there came several Limited Editions in '92 based on the Vogue with TWR (=Brooklands) bodykit and glass tilt/slide sunroof.
Brooklands: Brooklands Green with light-brown cloth interior, no electric seats.
Windsor: luxury leather interior.
Ascot: Beluga Black with grey leather interior, the most luxury Classic (Vogue SE A).
Westminster: Westminster Grey, grey perforated leather interior, no bodykit but with chrome bumpers, mainly for the US and Middle East markets.
The bodykit is also sold as an individual package, so if mine is an original or a lookalike, I don't know.
Tony.
