Do you have a dataplate under the dashboard installed like this?



This should give you more information.

Hello sixbysix,

Once i had the same question about the year of built of my truck. I posted my question es did you on this forum. Then there was a man Gus Causbie that give me the answer. Thanks a lot Gus.

Now with his tables i can answer yours.

It is from august 1943

f you mail me then i can sent you copies of the tables and i can excplain how i came to this date.

Kind regards,

IL CCKW IN DETTAGLIO E LA SINDROME DEL COLLEZIONISTA

di Bryce J.Sunderlin

Tratto da ARMY MOTORS n° 53

PARTE VII - QUELLI DEL '43 I quarta serie:

I camion quarta serie, quelli costruiti dall' aprile 1943 al gennaio 1944 (numeri di serie da 213652 a 321077), erano quelli veramente standardizzati. Tutti erano a cabina aperta e con cassone in legno del periodo bellico. Dopo il primo mese di produzione, le modifiche furono poche e a distanza tra di loro.

PART VII - THOSE OF '43 The fourth series:

The fourth series trucks, those built from 'April 1943 to January 1944 (serial numbers from 213,652 to 321,077) were the truly standardized. All were in an open cockpit and wood chest of the war. After the first month of production, changes were few and distance between them.

The enigma GMC - Serial numbers and dates of delivery

The original motive of Tables I, II and III is the question "When it was built my truck?". Originally, it was hoped that there was a table IV, which gave the serial numbers for each initial and final year of production. It was too much, no luck. When it was conceived it was thought that this article would not be too difficult to make a guide for the CCKW that gave a summary of all changes in production and series production known (start / end etc..) so anyone could control a CCKW. Checking the serial number of the frame, you could say exactly what he should be, year, body type, type of cabin, and basic details. Well, that was the goal. Unfortunately it was not the result.

Recalling that the delivery date and date of production are not the same, I needed a bigger data base - a register of CCKW. A call was made at the end and began to leak information about serial numbers. The results to date have been less than spectacular. What became clear, different from the highly ordered series of serial numbers / date of delivery of the jeep (with their profusion of small differences) was that the progression of CCKW serial numbers, as of the date of delivery, was completely busted. There were large numbers of inconsistencies; media delivered one year after their sequence; media dated months before their alleged construction. For example, the following serial numbers and dates of delivery show that the oldest was delivered one year after the one with the highest number. CCKW 353-164011-1 (9-43) CCKW 353-173477-1 (9-42). Lest you think it is a case: 353-165412-2 CCKW (11-42).

These aberrations are not just isolated cases, they are very common especially in the chassis cab models with specific needs such as those trucks with the suffix -1 and -2. These digits of the serial number, -1 and -2, without a previous letter, mean the transmission type Timken (-1) or Corporation (-2), with or without winch, produced by a special body is not standard. The logic would say that this is not a problem. These special bodies were only 11% of total production, and thus may be scaled from the data base. More than 60% of the serial numbers / date of delivery have shipped the suffix -1 and -2 - I'm sure that some computer genius would take a day to explain why this 11% of the total production has the dominant share of survival.

The only way to run a block of deliveries based on serial numbers / date of delivery, is to base it solely on numbers. Production of the most common long-wheelbase, and those with suffix-AI-A2, B1-or - B2.

In addition, many numbers are needed to establish a reasonable sample. And THAT is a very long time ......

Surprisingly there is a valid explanation for these erroneous dates of delivery. The differences come from the fact that unlike the car (like jeeps) all medium and heavy trucks are delivered at the end of the assembly line as a chassis-cab. The military trucks are unusual in the fact that many of them come with a standard body installed by the manufacturer (trucks). These standards bodies are mounted factory-installed after the truck (chassis-cab) is completed - not the assembly line. With the chassis-cab trucks civilians is delivered and the dealer, or purchaser, the body adapts.

In the case of CCKW, while all the trucks were produced as a chassis-cab, the body type to fit was generally determined at the beginning of the assembly line when the chassis number was printed. The worksheet, which established the frame number and alphanumeric suffix which should be applied. The final code letter / number said if he had to be a transport truck with winch, transmission Timken (-BI) or a water tank truck without winch; Transmission Corporation (-G2). At the end of the assembly line of the frame, after the standards body was installed, the means were inspected and tested on the road (all defects corrected), the government inspector formally accepted the vehicle. That is the date of delivery, when the truck was complete and accepted.

All those special chassis-cab, were tested on the road, inspected but not truly accepted, because they still were not complete. From now on, the trucks were brought / led to the bodywork manufacturer / storage etc.. and languished in the system for a year. When the body and the load was completed at the end of the truck was still being inspected, accepted and only then was the delivery date printed on the nameplate nomenclature.

Because of small variations on contracts, depending on which branch of the army or those trucks were prepared specific (Transmissions, Engineers, Medical Corps)-that regulated the allocation of blocks of registration numbers, but there were exceptions to everything above. The first trucks of Lend-Lease were delivered without the registration number (hood), some were accepted and chassis-cab chassis-cab as outdated, some were outdated when it was installed the empty body, but most were accepted and dated when the entire truck / equipment was complete.

In contrast, deliveries of the Jeep had a very simple, neat. In fact, due to the complete absence of any optional factory, an anomaly in the system Jeep hours of purchase. With the G503, 1 / 4 ton, 4x4 production date and delivery date are pretty much the same. However, unlike the Jeep, is the incredible diversity of body types of CCKW, monthly and vacillating priorities on the type of body that cause the dilemma on demand "delivery date". And 'why can not you be more specific virtual in all cases when a change occurred, or the most basic answer to that question when it was delivered to my truck? What can be summed up is the need to have many more serial numbers and date of delivery before I can make a list satisfactory production.

In the tables, the patterns of production are the most accurate possible at this time by 1% or 2% - The schemes are based on production records GMC after the war, the U.S. Army and the list of production material published after the war. Between the two sources there is a discrepancy of only 1661 trucks. For the net amount of vehicles in question, this is amazingly accurate. Moreover, since these data are taken from internal documents there should be no reason to doubt their accuracy, although there is a big cloud over the extension of the serial numbers of the frame at the time.

In many cases, these patterns are inconsistent with those listed in the Book Summaries Contracts GMC Parts Main wartime, and also with the range of serial numbers of the frame. In the middle to the end of the war what was ordered and what was actually delivered were often quite different because the contracts were continually revised, corrected, extended or deleted. In addition there are the inevitable errors due to different counting systems: calendar year or fiscal year of production.

From the beginning, it was realized that there was at least one entire contract is missing, and the figures would not be balanced. In 1939, the French government purchased an unknown amount (at the time) of the initial model ACKWX. All recordings are lost with this purchase. So, there are actually more than ACKWX indicate the totals of the tables. Since the quantities are the total final production GMC 2 1 / 2 ton, 6x6 built from 1939 to 1945, when you know the numbers of missing contracts, the French ACKWX will be added to the volume of ACKWX, and subtracted from the total CCKW. In addition, the serial numbers of the frame is not running with the total production.

Theoretically, the last CCKW should have the serial number about 519,130, if the total production is accurate. But the serial numbers CCKW reaching 560,000. I do not understand this discrepancy, but nothing is carved in stone. Bart Vanderveen has patterns that give 562,750 GMC 2 1 / 2 ton 6x6. I believe that this is closer to reflecting the actual serial numbers. In the future will be made some adjustments to the tables.

In comparison, the Jeep enthusiasts who traffic with the data have the same amount of missing Jeep. Currently, there are about 23,000 MB that can not be calculated. Even the exact number of GPW produced is questionable. The final total Ford production (including adding / subtracting cancellations), the serial numbers of survivors and the acceptance of the U.S. Army figures differ widely. That's how well the "contapiselli" tenessero logs de1 material.

In the eyes of eagles who are planning to add all the numbers, and check my math, and send me a letter telling me that poison does not add up I know, all I can say is that the numbers quite right breast. Finally, when all this had been prepared, a request to the GMC had illuminated the answer: "The division of General Motors trucks and courier did not build trucks for the army". For years, a friend tried to convince me that the CCKW is not, no way a real army trucks. Maybe he's right. However, the GMC has no idea how these things built, or how they fit into the grand scheme of things the factory records are simply lost.
