Body number identification?
 

So i think i found the body number on my 28-M30 style truck cab but i cant figure out where it was made/when. It looks like AU3244 but from what i can tell theres no assembly plant called "AU".

it might be A then 03244... would they put leading zeros in the number? seems like i waste of time. Theres also no plants with AO or A0....

from what i know is the AA was a early 30 (old style sheetmetal, new frame/axles) and was on a farm in Kansas before it went to OK where i bought the pieces. When i bought it it had an old restoration at some point so who knows if this was even an AA cab and not just a regular A cab.

i see plant #26 is Omaha, NE possibly used AU. Do we just not know for some reason? Seems weird information to not know...
it makes sense being the truck was from Kansas.
