Decipher Manufacturing Process with Data Points

[Erv M.]

So this is how I understand this.

On Trim Tag:

C21 = October 21, 1965
STD = Black Vinyl
972 = Ermine White
A-1418 = August 1965 body mfg date

Vin Tag 104551 = November 2, 1965

Engine Stamp Pad is F1103HT = November 3, 1965


These data points are very confusing to me. In what order should the appear?

1. Body August 1965 - Body manufactured and railed to St Louis
2. Trim Tag Date October 21, 1965 - What is the significance of this date?
3. Vin # November 2, 1965 - sequential number of production
4. Engine Pad Stamp - Where should this date fall in the sequence of dates? Can this date exceed the VIN date?

Re: Decipher Manufacturing Process with Data Points

Erv,

Your last five of the VIN# are 04551 not 04557. According to the C2 registry, Approximate birthday 194375S104551: December 15, 1964.

The VIN in the photo is for a '66.

Re: Decipher Manufacturing Process with Data Points

Thanks for pointing out my typo, I have changed it. According to the TIM&JG the VIN is a November 2, 1965 date.

Now I am really confused how all this dates are suppose to fall into a sequence

With the VIN being 104551 is this not the 4,551 car of 27,720 produced?

The Body A-1418 does not stand for August. It is Body Number 1418 from "A" which stands for "AO Smith" and calculates to a Late October 1965 production. This fits within the sequence of your Corvette

Thank you, one data point confirmed. Still looking for someone to explain the sequence of manufacturing

Re: Decipher Manufacturing Process with Data Points

I have C21 as Nov 21.
October would be B.
I don't believe you can pinpoint AOS body 1418 as Nov 2 build.
I think your numbers line up.




add:
I still have much to learn.

C21 is based on a A.O. Smith built body. I think you are referring to a St Louis build date.

Re: Decipher Manufacturing Process with Data Points

The engine assembly date cannot normally be after the car assembly date. Could you post a picture of the pad and advise engine case casting number and casting date?

Re: Decipher Manufacturing Process with Data Points

Thanks, Michael. I should know better than to reply to a thread without having my "cheaters" on...most certainly is a '66.

Trying to get back to the question I asked:

The C21 do we agree it is October 21, 1965 as this is an A.O. Smith Body
The VIN is a November 2, 1965
Pad stamp is November 3rd


Is this the correct sequence or should the dates follow this sequence below:

Trim Tag
Pad Stamp
Vin Date

Erv, the pad stamp can't be after the build date unless they blew the enging in the parking lot and it had to go back to repair for a new engine.

Also, How was the November 2 calculation done? My Birthday calculator has that date but it's not always 100% accurate as it does not take into account cars built on second shift. That adds a day.

Re: Decipher Manufacturing Process with Data Points

Harry:

So do you agree the body build date from the Identification Tag C21 = October 21, 1965? (I am pulling this from the TIM&JG guide page (6) )

As for where I got the November 2, 1965 VIN date someone gave me that information. Since the last VIN in October was 104384 another 167 cars were built to reach mine at 104551 so it made since.

As for the PAD STAMP are you saying it must be before the VIN date or both the VIN date and Identification Tag date?

In the TIM&JG it has a definition of "Approximate vehicle assembly date" what stamping on the car defines this?

[Harry S.]

Re: Decipher Manufacturing Process with Data Points

The Pad Stamp date can be equal to or before the VIN date not after. The Shipping Data Report that you can obtain from NCRS gives the date the car was built, well maybe. The information NCRS is looking at is on Microfiche. It displays what VIN's were to built on a given day. This is as close as you can get unless you have Copy 5 of the Regular Commercial and Truck report. This document was partially typed and handwritten. Additional information was added when the car was near the assembly line. The person at that spot looked at the car in front of him, checked the VIN then looked at the clock for the date. Then he typed the date on the document. The car was essentilly finished (engine installed, etc). So if the Shipping date report says November 3rd and the car was at the documentation station at 1 minute past midnight the build date is November 4th. Very few, probably 1% or less of the Regular Commercial and Truck reports were given to the original owner and less survived yill today. It essentially the Holy Grail of birth certificates.

The Regular Commercial and Truck report accompanied the car to the dealership. The dealership either threw it away or put it in the glove box.
