P-T-B

[allcamaro]

When puttting the PTB on the firewall was the ( B ) put on before the painting of the car or after? I would assume the P was after, and the T was also after the paint was on. If this is true would and could the ( B ) have some overspray from the body color.

That is a very good question. I would ask Jerry MacNeish and Brian Henderson and compare notes. [img]/ubbthreads/images/graemlins/dunno.gif[/img] Sam

I have many photos of original untouched firwalls and I have never noticed any overspray on the 'B'. I even put some on the computer and did a CSI style blowup. Cannot see any evidence of body color. Good question though...BKH

Brain, I have been told by a reliable sourse that the PBT was the last thing Fisher Body did before the body (firewall back) was released to the Chevrolet side of the plant. There were two inspectors at the end of the line who check the P-paint, B-body(sheetmetal) and T-trim. So, the markings would be on top of any paint.

On a side note, the firewall crayon markings will be under the firewall paint.

That is what I have always seen. Thanks..BKH

My LA built JL8 car had the broadcast sheet sequence # written on the firewall on the driver's side. It was hidden by the fender so it was in good original condition when I took the car apart. I could't tell if it was chalk or crayon, but it was written on top of the black firewall paint. There was also some writing on the center of the firewall that was either "72" or "Z28" and since my car is Hugger Orange, I thought it was "72". It appears the LA plant did things differently than Norwood.

I agree......my Van Nuys 68 Z28 has what appears to be "Z28" in crayon under the heater core cover. No signs of P-T-B on the firewall as Norwood did.

Can anyone else shed light on this subject?

in the jerry macneish Z/28 fact book there is a really good picture of an original firewall with the PTB stamps on it. if you look close you can see the overspray on the "b" as if
it was stamped on before the body was painted the color.
the picture is on the top of page 184. hope this helps!

Z28's (and Z10, Z11's) may have overspray on the PTB stamps becasue the front stripes were painted by GM in their paint line, not Fisher. If the plant (most noticably Norwood) got the stripe color overspray onto the firewall, then they would need to touch up the offending areas. LA seemed to have a much better masking system then Norwood and hardly ever got overspray onto the firewall. although they also did not use the P T B stamps. Orange PTB stamps indicate the car was inspected during day shift, Green PTB indicates night shift. People with two different colors just reapplied them wrong. Norwood was pumping out 52 to 55 cars an hour, I doubt there is a situation where one car had one or two inspections on day shift and the remaining ones on night shift.

MARK C..Hi I'm in Arlington Mass!...I have 2 Norwood 67's..One had a P on the cowl side (door hinge area). My Pacecar has no T's? The P&B are visible under the blower motor but have white spattered paint ontop of them..This paint is also all over the passengers side toe board area..I cannot figure that out and I'm the first guy in there since the factory.. On the drivers side I have a P&B on the "X" shape behind the fender..Next to them is orange grease pencil that says " TOP OK ".. It was obviously written before the nose went on but I wonder if it means the mechanical function of the manual top skeleton or the fit and finish of the cloth? Anyone else ever seen this? I've never seen green anywhere and I've had 4 norwoods apart that I ever bothered to check for. My front fender extensions have very large white grease pencil RSC 's written on both sides..I assume Rally Sport Convertible as those two distinctions bore relevence to what the nose would be ( vibration canisters and hidder headlamps) Anyone ever seen that before? Thanks Tom
