Thanks to Bridges' Studebaker's Finest, I found the paint "tag" (which is a piece of paper) affixed to the firewall on the inside of the car behind the glove box. It fell off as soon as I touched it, so I brought it inside, put it in a ziploc bag and left it in a safe place. So, is Ivory Mist the original color? Did someone else add the two-tone later, or did the original owner, in a moment of passion, decide to order his plain-jane car with a splash of style?
I'll not know for sure until the original production order arrives, but unless a previous restorer faked the paint tag, here's what I found:
Ivory Mist and Maui Blue. But does the tag lie? We'll find out soon.
