It's the additional lens over each headlight that tipped me off it was a 6V bug.
When VW upgraded the bug to 12V, that extra layer of glass on each headlight went away.
R5:
What absolutely baffles me about that is:
though society was fluid, the VW beetle became a reliable, recognizable standard.
It developed not only brand loyalty for VW, but model loyalty as well.
Certainly there were "improvements" as the model years progressed. BUT !!
VW did not do as automakers tend to do today, and increase a model's size from one year to the next.
Not only did VW save a fortune on R&D for unworthwhile, gratuitous changes.
Though VW automobiles had longevity superior to many competing brands, the stability of the VW beetle
was enough to establish repeat customers.
It's not merely tragic, but baffling that some other automaker doesn't enlighten their own marketing to this -everyone wins except the competition- formula.
PS
I never tried it, though I push-started a VW minivan around 1:AM on a school night in my miss-spent youth.
Reportedly those old ~40hp air-cooled horizontally opposed 4 cyl VW engines could be started even if the battery was too dead to turn the engine over.
The report said, jack up one of the rear tires off the ground.
The VW transaxel wasn't posi-, so leaving the opposite rear tire down left the fly-wheel directly connected to the engine with the transmission in gear.
The report said, leave the transmission in a gear, 2nd or 3rd I imagine, and manually twirl the rear tire that's off the ground.
Again, I never tried it, but the suggestion is, in a pinch, it can get the engine running.

Volkswagen in English means people car.
Kübelwagen in English means bucket-seat car. The KW was used off road, rough terrain, & therefore was equipped with bucket seats to help keep passengers aboard.
