Today I found another 1950 1 ton here in Minnesota that was built in the same plant and the same month as my 1950 1 ton. The last four numbers at the end of the ID tags are only a difference of 282 trucks. So I would think that this truck and mine were probably built in the same week (just guessing). Did those numbers include all the different truck models or were they only for 1 tons? If it includes all models, then my 1 ton and the one I found today may have been built close to one another if you just count the 1 tons out of that group of 282 truck. This probably sounds confusing, but I thought it was kind of neat to find a vehicle built numerically so close to mine. Tom

Good question. I don’t know the answer. But I think the sequence number includes all models.
I have noticed that the stamping of some serial numbers is different front to back: the characters for assembly plant, year, series and month may be larger or different font than the sequence numbers.
Example: 21HS-I 4465. Have others noticed this? That’s one reason I think the sequence number includes all models.

The vehicle serial number is for each series at each plant (subtract 1000 from that serial number - in other words, starting at 1001 from each vehicle assembly plant).

The engine serial number is a sequence number starting at 1001 at each engine plant.
