The Stovebolt Site Forums The Shop Area General Truck Talk Firewall chalk/crayon marking

First of many questions to come. Just starting restoration of '51 1/2 ton.
The firewall has JB (script) written on driver side.
What does this represent?
I will post picture once I figure out how to!!

No one knows what it represents. There have been various markings reported here over the years and it's anyone's guess what any of them meant.

I have a large X on my driver's side firewall marked in yellow crayon. Truck was assembled in Oakland in early 1953. The X was placed there after the body had been painted its coppertone color.

Somebody told me years ago, that markings on the firewall like that, are the final inspectors mark when it came off the assembly line.
Don't know if it is true or not, but it does make sense.

...and a recent article by an assembly line worker from the later fifties said sometimes it was the previous workers initial signifying his job was done.....in one case the markings were under the fender on the inner fender and to keep from bending over they would hold a mirror under the fender to see it.
Many have reported that some marking also indicate trim, engine and so on, or other options as it went down the line.....and that it may vary from plant to plant.

I see 23

Digital photos can be deceiving, but your pickup appears to be Yukon Yellow (code 234M) rather than Coppertone (code 234R). Of course, the exterior was likely refinished a few times over the past six decades (time flies) while the firewall could have been left untouched

Interesting,,,I dident notice it until you mentioned it...could be..

Yeah, my 57 Bigbolt LCF has all sorts of markings on the firewall. "STD", which I guess was standard transmission, "deluxe heater" self explanatory, and several numbers that make no sense. I just think it is neat that those have survived for 57 years. I am changing colors on mine, but do not intend to paint over the firewall with the markings.
