VIN range issue for 1974, VIN Numbers Options

[Bse30]

New member here with my first 914.
I just picked up a neighbors 1974 914 2.0 that has been sitting since a left front accident in 1995. Remarkably good shape, otherwise.. It was stored in a garage from 1995-2019, covered in front of garage next to my place since then.
I bought it from the family after he passed.
I entered the VIN knowing it was near the end of 1974 production. Build date of 8/74.
Website says it is out of range for this model year.
I’ve found at least 3 different references stating ending VIN is 21370, and at least 3 state last VIN is 21379. This car is unequivocally 21378. All documents and 3 clear VINs match. Which would make this the 2nd to the last 1974 made if I go by the second source.
Any thoughts? Is this the norm for other years. No big deal, just somewhat interesting to me.
Thanks

Very strange. I always assumed 914s produced in August (after the summer hiatus and re-tool at the factory, were for the following model year. My '74 is dated 8/73 and follows suit. Guess this is a unicorn. Or is something stamped wrong on the VIN label?

The final assembly , and thus the dates on the compliance decals can run later than the summer break. Note that all of the 1974 model year cars have weeks up to 28 but the 1975 model year have weeks starting 32, so there was a month long gap in chassis production, but not necessarily the final assembly.

Yes, the HC campaign was to replace incorrectly dated compliance decals, but this is a known hiccup regarding the dates.
Notice the HO campaign has the correct VIN ranges for all years.
