PTB stamps backwards P meaning?
« on: April 03, 2016, 04:29:26 AM »
So during the time I have been documenting my 68 ss350, I seen that one of the P stamps are backwards. Any reason or meaning why it was backwards?

It failed Paint review.  ;D  Just kidding! I've seen a few over the years but have never heard or read any reason other than maybe an inspector did it that way possibly to distinguish he did that one.

I wonder how that stamp was acquired.  Or what the stamp they used actually looked like.

Does anyone offer the stamp to duplicate the backwards "P"??  I don't recall seeing that anywhere but it would be nice for others, including Butchie,  restoring these cars that want to duplicate the quirks that are found on quite a few of these things.

 My guess would be it was just a manufacturing error which had gone unnoticed until it was used. Then used until it was replaced with a correct one. Being there were Camaro's rolling off the line every few minutes I'm sure many were stamped with the defect. I think it could possibly be a defective 'B' with part of the top portion missing so a quick glance would look like a 'P' but not realizing it was reversed.

Interesting.  Most of the quirks I see with the stampings, they aren't backwards, just upside down.  But I could see how a B missing the top would look like an upside down AND backwards P, lol

  That's what I think it's a defective 'B' that an inspector mistaken for a 'P' and not yet realizing it was reversed as a 'P'.

Mike, I should clarify as I agree the reversed "P" is what has been noted and what I was referring to earlier in my post but someone did post a picture before of a reversed P.

Hi Chick,

  I think one way the OP can get by this unique stamping is to perhaps tape (maybe the firewall -or- the stamp) the missing part of the 'B' to duplicate it. Or better yet, preserve that area to show it's truly original and unique.

So that would raise my question then, as far as duplicating that on a car since all I've seen from vendors are simple PBT stamp sets.

I'm thinking one could buy an extra B, remove the top portion, then flip it upside down and you would have a right side up backward P.  Hmmm

With these sorts of stamps, if you are going too fast, and don't ensure that you've stamped the full letter/character, then it's possible to get only a partial stamping, even if the full stamp letter is present..  it might be interesting, and prove/disprove the point if someone who has a 'B' stamp, tries to stamp it 'not squarely' and see if you can produce an upside down/reversed 'P'....

Here is a picture.  IMO it looks fairly different than a messed up B.

At first it looks like a backwards P. Looking closely I was thinking a double stamp. The first one they got the left side of the P, and then re-stamped lower and only got the loop ? It looks like a raised bump may have prevented the first P ?

If you enlarge the photo and look at the lower loop there is evidence of the top half of a "B" being cut off.  Look at the bottom loop at the point of where the top loop would have joined the bottom loop.....the arc of the loop is not very smooth, it is rather irregular like the top loop has been trimmed off there.  It also appears that the top part of the upper loop has been trimmed off at the upright....there is a bump on the left of the upright but the right side is fairly flat.

Is this the one you are referencing?   If the stamp company screwed up and produced the 'P' stamp backwards, it would/should have been caught very quickly I'd think once used...  :)

Yes!  Maybe it was the Norwood  fisher employee "John doe's" calling card. "Yes I was here and put on this groovy stamp!"  Haha 😎

That could have been the same guy who wrote he was here during WW2 and Korea and later landed a job at Chevy during the '60's.  8)

Another possibility: They need a P and so modify a B into a P, but screw it up.

On these cars with the backwards P's do both sides have the same stamp?  Inspections were supposed to be done by two teams one on each side of the car as I understand it each with their own stamps.  If both stamps are the same it might mean something, if only one side is backwards its probably a custom made or repaired stamp.

There is another PTB on the passenger side and the p is correct there.  Drivers is backwards
