  Interesting you mention 'ink". I have see a few original stamps and they look like a high solids ink to me instead of paint.
 Before I stripped my firewall in the 80's had only seen 2 stamps out of 3 on each side so that is all I put back on the car.
Back then there were no stamps for sale and the meaning of those were unknown so I made my own with tracing paper and rubber and very thinned model paint. Now, from CRG I learned that there was also a green color used and several original example pictures posted show the green being faded more than the orange. I'm sure not that must have been the case with my car and didn't realize there was a green because I only looked for the orange.
  Anyhow.....I'm going to try a high solids ink this time out.

Well my car only has the green on it, luckily nobody ever thought to " clean " up the engine compartment . But you can see the B was a lot more crisp than the P or the T.

Has anyone thought about the possibility of Fisher Body use a stenciling "INK" not paint.
Stencil Ink does not have the same consistency as traditional paints.
just a idea.

We use "Stenciling" INK to label Electrical Bussing and mark Naval circuit breakers for various hulls in the DoD side of ships repair all the time.

It does not cover very well and stamps crisp and fades with time, ,,,

Believe several of us have been saying that for a few years. Wish we would find out from someone who worked there.  It has never looked like a paint to me due to be so transparent and thin in thickness.

When I restored my 67 RS/SS, I found the original PBT stamps on the firewall behind the fenders. They were definitely some kind of ink.

The stamps I have look nothing like the originals when you compare them side by side. I am trying to find out if there is a supplier out there that makes a more accurate stamp.

 I wonder, was there some order the stamping occurred?  Was the car inspected in a certain sequence?

All three inspectors (Body, Paint and Trim Shop) were stationed at the end of the Fisher Trim Shop, just prior to the point where the body was shipped "through the wall" to Chevrolet; they worked independently.

Hi John,

  I assume it was a serial inspection method, so was it body first, then paint and finally trim?

Happy Holidays,

John,  We all really appreciate your information and perspective, and I have a couple of questions concerned these 'marks' (understanding that I owned my car for over 30 yrs and never *saw* them, until getting on this camaro list.. ..
1)  Why do some cars have the P T B on both side and and some only one one?
2)  Why do some cars have multiple stamps on one side of the car?  ie. My car had two T stamps... (one down below the trim tab)..
If you don't know of a specific reason for the above, I'd appreciate your 'best guess'...?

Hey Gary my car had 2 Green "T" stamps on the drivers side and possibly a red "B". Those were the only remnants I found on my car. Not sure if the other letters faded away or wore off, of if that is all there ever was on the firewall. From what I am reading so far however it sounds like all cars got all of the stamps. Also note that some cars had both colour stamps on different letters, which seems to be a much rarer occurrence, that all one colour.

So does the green vs orange hold true if inspectors rotated on and off-shift independently and only cars which came through during shift change had the POSSIBILITY of having different color stamps?

[Jon Mello]

Jon Mello had a picture of those brackets he took off his 67Z back in the day.

Chick, just to clarify, I did not take those spark plug shields and brackets off. They were from my green '67 Z that I bought right from the original owner. The car was a factory header and cowl plenum car and the headers were installed the first week he had the car. Everything that came off was kept and put away by him. The exhaust manifolds and the sections of exhaust pipe that were removed (that were the length of the headers) were absolutely pristine, as were the shields, etc. I had no doubt they came off the car when new.

[BULLITT65]

good story, makes you want to give the seller an "atta boy" pat on the back. Also neat to get the items removed with the car. How many people would have the forethought? Not many I would think. Plus as Jon says definitely backs up the story

We'll probably never know, as things/people changed from day to day; those folks were "Final Buyoff" inspectors, the last people to look at the body after line repairmen and line inspectors had worked off any open items further back on the line. If a body didn't get a "B", "P", or "T", it didn't go up the hill to Chevrolet until it was repaired and bought-off.

So about the only way you could get a set of multi colored stamps was if 1 or more of the inspectors was happy and put their stamp on, and the 2nd or 3rd rejected the car for his area.  Then the car had to be repaired for whatever caused it to be rejected and then got reinspected on another shift.  Say the Paint and Body inspections went well and got orang stamps, but a peice of trim was messed up, or incorrectly installed and got rejected.  The car got pulled aside and someone would have to come and fix whatever the issue was before the "T" guy could affix his stamp.  If the car was originally inspected near the end of a shift, it could be the next shift before the issue was resolved and the car reinspected and stuck back onto the line.  So now you end up with orange P, and B's, but a green T on your firewall.

I'm assuming they had to pull it off line at the final inspection point if it failed to get the issue resolved because there would probably be very little time to fix it between the inspection, and the body going thru the wall the Chevrolet.
