There were two Dealer Books! Two sets of paint chips!
There were two dealer books one with the original colors and a later one which included the "1957" paint chips.
I have a 1956 book and it matches the paint samples that Holger posted. I didn't know there was a 1957 book until I visited Rick Schmidt of NPD, Ocala, FL in 2014. I went there to see the Ford brothers' cars which they had restored.
While there, Rick showed me their Dealer Book and I saw that it was different from mine. I didn't know there was a '57 book and Rick and his father, Jim, didn't know there was '56 version of the book.
When Continental closed down they told the employees to take what they wanted because everything was going to be thrown away. An employee rescued the Dealer Book from the library which subsequently ended up in the hands of Rick's father, Jim.
I think I may have a photo of the '57 book's paint chips. If I find it I'll post it.
