Pete,
Don't take a wrong turn. I'm pretty sure those are pre-computer "renderings," not photographs. Totally dependent on what color crayon the artist used.
The most accurate, non sun-faded information would be obtained from owners who had one back in the day, or their pictures. Or even better, if you could
find someone in Ford's Trim Shop in Quality Control who inspected them when received. (Dreaming!!!!)
There's no way to tell if the Horse Strip and Bolsters matched, 50 years later.
