I have the original set of Kent alloys for my XJ6 built in March 1986. They have been used heavily. I also have a new set of the Kents. There is a slight, but noticeable color difference between the two sets, with the used original set being lighter - both the gray and the silver colors.
Does anyone have the color codes, or known colors from manufacturers available in the U.S., appropriate for the time period around March '86 for both colors?
