Jefferson plant did not code a lot of items to begin with. That tag would be typical for that make and model and how it is equipped.
Not all options, regardless of 'major' or 'minor', are coded on a tag especially at a a plant like Jefferson. Jefferson plant tag coding protocols were different than other plants. What was coded at Belvedere, Windsor or Newark differed from Jefferson.
Options that require a hole punched (antenna, tachometer, moldings), a bracket (console/buddy seat, cruise), or BIW panel modification (radiator support, cowel, dash), driveline, paint and trim are, typically, coded on a tag. Suspension, wheels, steering related items, some power related items are, typically, NOT coded. Exceptions and variations exist depending on the year, plant and coding protocols of each plant but that's usually the basics.
There is no way to know how 'well' or 'stripper' of a car you are looking at simply via the fender tag. There are numerous and hundreds of dollars of options that are not coded on a fender tag.
Based on evidence from other plants, pilot cars of that era typically carry July SPDs a low VINs (<100). Promo cars carry an 801 SPD and, usually, an out of the ordinary VON.
So while this is certainly a low VIN and 'early' car there is nothing particularly telling from the VIN or VON number that this car is anything other than either an early sales bank car or ordered car.
Here's a standard 383-2bbl manual transmission (Just like Cbarge said above) Newport ordered without a radio. NOTHING coded other than drivetrain, paint and trim.
