As 1966 head judge I agree with this decision 100%. However, I do not understand why the points on the car in question would be reinstated due to something found in the archives. In the past 30 years since I have been a head judge we have changed judging rules and scoring on various items at least 6 times (without the approval of the board). The current sheets were just reworked few years ago and many point values changed and some things that had been allowed in the past were revised. I personally do not ever remember us ever allowing a color change in any of the classes, but if we did back then, a lot of rules have changed since then, and it is very clear on the current judging sheets that it is a mandatory 30 point deduction for a color change. We learn more about the "marque" all the time and the judging rules over the years have been changed to reflect this new knowledge.
Having said all that, the decision of the board is final and I accept that. They are the ultimate authority and I will abide by whatever decision they make.
