Crayon Marking on cowl above heater

[z281967cam]

Just wanted to know how important this is on my newly acquired 69 Z28. The car is code 72 Hugger Orange, so I am assuming this marking was done to alert the line workers of the color of the car. It is very visible as OR. FYI this is a November 4th week of 1968 Norwood car.

That was done during body fab prior to paint.

The last paint step was firewall blackout, which covered any firewall markings. The paint did not adhere well to the to grease pen and the markings became visible.

Random markings made after paint have been noted. Usually its the 3-digit final assembly sequence #. I have also seen the last three digits of the VIN.

Other than the heater hose, looks like it could have a lot of originality. Post up some more pics when you can. Thanks.

My burgundy car has MAR there for maroon.  weird they didnt use BUR.   I found all kinds of markings after soda blasting the rest of the firewall.  N10 and other numbers.  Would be neat to see one marked up before it was painted
