The way I read the table (which is from the 1939-53 GMC Light Duty Truck Master Parts Book) is:

25322C1694

25 One ton
..3 137" wheelbase
....22 228 engine
.......C built in California
.........1694 Chassis serial number

So it would almost fall into the second to the bottom line EXCEPT C1694 is lower than the published numbers C1775-C2495. I'll check with some of the guys over on the OldGMCtrucks forum to see if maybe the 3rd line from the bottom actually should include a P, C or S "Plant identifier".
