Title: Willys Identification
Post by: Ryan_M on March 30, 2014, 08:23:33 AM
Here's a pretty informative write-up and original Willys service bulletins to help identify that Willys barn find you just discovered.

I tried to upload the actual PDF here but the file size exceeded the site's limitation. Not sure if it would be appropriate for a moderator to permanently post it somewhere on the 3A page or not.

Thanks Ryan. I was told '52 and the key tag said '50's so this helps me a lot.

Hi,

my CJ3A, SN 38604, has been produced earl in 1950. I cannot find any more precise information - month for instance.

Has somebody some figure. The owners of the nearest SN in the database have no detail.

Thanks.

There is a possible typo in Bob Westerman's book during this time period. Based on his other data,  I will speculate that 38604 was built in early to mid September 1949.

I'm not seeing what you are referring to???

Hi Bob,

Page 60.

CJ-3A 392xx Estimated build date mid-November 1949.

Followed by,

CJ-3A 409xx Estimated build date mid-October 1949.
CJ-3A 415xx Estimated build date early November1949.

The timelines seem out of sink with the listed serial numbers,
So I guessed that you might mean 392xx was actually mid-September?

Tim

I see what you are saying. That is not a typo. Those entries were derived from data obtained from surviving original vehicles. Even when the data did not fit the expected pattern, I still included it. Maybe the vehicle wasn't so original after all. Maybe someday the data will make sense. In any event the data is there.

Trust me Bob, I�m not making judgments, or questioning the data you compiled.  Your book is my Willys Bible.  This is the only thing I�ve ever found that didn�t make sense. 

Knowing how little raw data there is on the 3A, and how many things can happen on 65 year old vehicles, I'm constantly amazed how well your book fills in the gaps.

But still a  question:
What about the Body number?
The above quoted lists deal  with chassis numbers.
Are they identical?

The body tags disappear early in CJ3A production and never return.  I don't know if the body tag ever matched the serial number.  My 1949 CJ3A with serial # 13655 has a Body tag #13115

A difference of 540 cars produced "chassis only"?

I can�t tell you why there is a skew like this.  Anything I would offer is speculation. 

Bob W is the true 3A historian.  He may offer some ideas as to why.  I recommend his book to anyone interested in 3A history.  It, along with other documentation, will likely leave you believing that Willys Overland took their eye off the ball with regard to the CJ3A.

I have not picked up my Willys yet, but I did get the old title in the mail.  However, I cannot decipher what it actually means.  I guess I have to wait until December.  I feel like this is Christmas...I cannot wait!
