Handful?  lol  - - - I have shoe boxes full of all of those.  Plenty of those #1s were on the 1969 cars.
And no way can you say that only one version is correct and the only style used.  At least 4 different vendors at that time - - all with slight variations.   Been pulling these from Junk yards for 30 years.  Pretty darn positive about this....

Great and interesting but can you show some survivors with those #1 valves! I have not seen one survivor with that type valve and agree 100% with Mike.

I agree Steve! I purchased one to review and yes, very close and 100% better then those that come on rebuilds or new repro's.

I am not talking about survivors, those are always suspect anyways.  I am talking about cars that were crashed back in the day and have been parked and untouched since then.  Those are the yards I went to for 30 years, and where I grabbed and observed all the different examples.  I have 1000's of pictures, bet if i go through the crates (not digital - Fotomat) I could show you.  One of these days sir....   One of these days...  :)

these are some i just had laying around the house.  The #2 (not shown) is on both my 67 cars. my 69 is wearing a #1.  But many of these others are still correct for those years interchangeably...

Would have had more, but the wife keeps putting the boxes in the garage when i am not looking and i can't find anything anymore.   lol

Actually looks like a bunch of valves off later 70's and 80's cars to me. Know what you mean about parts as the wife was not too keen about using the kitchen stove and dishwasher for parts. LOL

Ones on the Left are all early 60's.  look at the top left - just like #2 but no hole in the center.
The small hose // large Booster hole - are Midyear Corvette Z06. 
67 Camaros could wear any of those others on the left with no questions in my mind.

I have been observing these for some time - was thinking of writing an article for the NCRS one day.
I really am darn positive about these.  - the 80's valves look nothing like any of these. Others as well as the multiple circle style were used into the early 80s)

many vendors made these valves, as well as all the different parts for GM.  Millions of cars- millions of check valves.
lots of versions.  thanks.....

Jeff, its a good topic and one to be aware of but I have tried to research this the last several years and have not once found what your stating on any 67-69 Camaro. For example, go to the CRG's http://www.camaros.org/forum/index.php?board=20.0 listing of original cars and look to see what valves are noted. Everything I've noted is type #2. Can there be exceptions, I'm sure there are but I'm still looking and it would seem to be rare. Can you show an example of a known survivor with that #1 or #3 valve?

I'll venture that different plants used different sources. So a 69 Camaro might be only a couple of versions, where as a full-size (with all those different plants) could have many suppliers / versions.

Which is exactly what i am saying. Both plants produced other models along side the Camaros.
Even a plant as small as St. Louis which only produced 1 model -- the Corvette. has variations of many items (including check valves)

To say or even believe that every 1st Gen Camaro only used one style check valve is really inconceivable.
But I know what I have seen, I am gonna check my boosters when I have time, I have 20 or so 9204s and 3 or 4 8515s hidden somewhere around the shop. They are all unrestored in "as found" condition - - don't remember if I left the valves and hoses in them or not.

I have a huge bin full of hoses tons of valves attached there - - will look for paper tags to ID them. 
been a little cooler here lately, was too hot up on my 2nd floor to go digging.

Actually, no. Norwood only produced the Camaro in 67-69 with the Firebird added later in 69.

Attached to original boosters would count. :)

No Luck
At one point I was gonna restore all of the boosters and send them on their way.  so....,
Unfortunately I pulled all the check valves, pipes, and hoses - put them in a separate bin.  I never took the manifold vacuum ports either.  :(

Sold off 100's of the various check valves over the years, did not leave the paper tags on them.   :(
Still have a ton - -found 5 or 6 of the #2 right on top.

I have the #1 on my 69 Z11 - it came like that 20 years ago on the original booster.
That's kinda why I don't trust survivor cars so much - If the new owner believed (wrongly) - that his check valve or other part was not the one
everyone expected to see, he would just change it to the desired flavor at the time.

Like the dipsticks, oil plugs, and many other items - the believed "typical norm" seems to change from time to time - even though all versions are technically correct.

I did take 1000s of pictures in the yards. We traveled to many remote areas, most of the pics are buddies bent over picking, goofing off, or HUGE fields of cars. Lots of pics of really rare cars that just weren't salvageable (at the time) OMG  lol ?

So I guess I can't offer any forensic evidence at this time.

But I can tell you that I have seen, and provided parts for -- many Nationally Certified Survivor cars where parts had been changed in the past. - I will never tell..  lol
