Special Spitfire steering wheel?

["Ian Frearson" <frearji@montevallo.edu>]

Quite a few years ago, I saw a 79 or 80 Spitfire with a steering wheel I'd
never seen before, and haven't seen since. I don't remember whether the
wheel itself was leather-covered or the standard rubber, but the center
insert, which is usually just a flat aluminum disc with very plain "Triumph"
lettering, was in this case a much more elaborate "medallion" with the
Leyland "L-swirl" logo in blue on a white background. Anyone have any
insight as to what the story is here?
