Jeff,
It would make sense that a build sheet would exist for the BP line, too. I guess I was just trying to find some evidence of their actual existence.
Believe we will have to rely on comments by workers not sure where one would be located to make it through the build and paint process so that we would find it today.
I don't have any 1966 special order paint build sheets in my possession, so I'm not quite sure how the process was handled..............., I normally see a 6-digit DSO. The first two digits being the region district and the last 4 digits I believe are the particular order number. Nothing about the paint code here.
We've seen (other years) were the Specials got other than four following digits but the vast majority as as you describe
The broadcast sheet however, is supposed to indicate the special paint color in the last box of the top line DSO/FSO/PTO (Domestic Service Order/Foreign Service Order/ Paint & Tire Orders). Was there a master catalog of paint codes that the code referenced?
. I would guess that in 66 they marked the buildsheet like one other years. We've seen where a note was included on the bottom of the sheet stating things out of normal production such as kilo speedos on exports, different steering ratios (than standard for particular model so that that point would be noticed by someone on the line. In this way it would call to attention a special or different paint for your example.
On the later ones there is a note (printed out when the buildsheet was printed) simply. The notation was "SPECIAL PAINT" followed by the paint code. From there the painter have to mix the paint (unless it was once from a different line of car that they assembled at that particular plant. Recall one of the painters mentioning how that process worked (application of an odd color) outside of the regular feeders - just can't recall the details at the moment
If the build sheet was one of the few places to contain such information, it would make sense that the BP line would be working from them as well. After all, one of the first things the line has to establish is the color.
Not sure if I understand why "one of the first things" would be to establish was the color since that was not going to be applied until later - after all the panels were assembled, sealants, some sound deadener and other body panels were installed.
