Very interesting, Tootallmike, so as my CCKW352-B1 falls in between chassis numbers 13188 to 41188 I can assume that my truck was built between Feb 41 and June 41 ???


:-D :-D mine is an early truck...... :-D :-D

I have tried looking for my chassis number, but it's not there!!

I have bared the metal around the front off side spring on my 353 and found nothing.

Strange, though, when I was stripping the paint off, there was a paint run that went upwards, yes upwards!


Is there any other way of ID-ing the Jimmy?


Cheers, Ash.

Found my serial number just in front (to the right) of the shock absorber assembly (pic below).

My friends 353 (same contract but Jan 43 production) has the serial number to the left of the shock mount. His is CCKW 353 I79xxxA2 (note the use of I instead of 1 - similar to what has been found on jeeps) but my serial number has the number 1 (as per the picture).

Both have Circle/164 to indicate the 353 chassis, but mine has an additional S/Circle before the serial number - no idea what this relates to, or even if it's factory applied.

Just to say that on my truck, a CCKWX, the chassis number is just 4 numbers (it was manufactured in late December 1940), without a prefix or suffix. This is on the right hand front chassis rail as usual, but is also on the left hand rail with the numbers upside down. It would seem that the need for extra nomenclature i.e. CCKW, 353, B1 etc was only introduced after the first production runs.
