I know this reply is reviving a thread after 7 years but maybe this will help. This is a 1955 1st series two tone deluxe cab with Mariner Blue lower. I think this is the "Bombay Ivory" that was mentioned for the top. It was painted over with a crappy white top but I'm stripping that to repaint the truck. The wheels were also repainted white but as I removed that paint, the wheel stripes on the Mariner Blue wheels seem to be either white or the Bombay Ivory as well.
