And the VIN is J53B027999. Book says they made over 40K 3600s that year, so it was not an "early" one.
What book gives model (3600, for example) production number by years? Does it have all Advance-Design years (and, production numbers by series and by each specific model, 3604 for example)?
I have a few production number documents and they show the following for 3600 trucks:
1950 3600s = 66,581
1952 3600s = 38,717
1953 3600s = 40,617
