Paint Code Decipher help

[jocko]

Quick question for y'all... I've noticed the following:
- white top/solid body color trucks list their color on the SPID as "white & color"
- white top/upper body color/white bottom list their color on the SPID as "white/color/white"
and, last but not least, that -
- white on top and between upper and lower body moldings list their color on the SPID as "white/color/white/color"

So, I'm looking at this truck with ACTUAL current paint of white top with white between the upper/lower moldings - and ochre everywhere else. I expected the SPID to say: white/ochre/white/ochre, or something like that.
But instead it says: "white & ochre" (only). Seller claims it's original, and that's believeable when looking at the paint closely.

Wouldn't that mean that originally the truck was a white top only with solid ochre body?? In other words, what I believe has happened is that the white mid-body paint has been added to a whote over ochre truck.

BUT....

SPID code is 463. Which makes NO sense to me - plain ochre was 511 in 72, so, tow tone would be some variation of the middle digit on that, or so I thought.

Appreciate your help.
