Well, I'm not certain, because the photos are of the car owned by Righini and aren't that old. Certainly the original units could have been replaced with modern ones since the car was built, circa 1939/1040. The second car was destroyed long ago.
Here is yet another modern photo of the Righini car. It is really hard to tell what shape the actual headlight units are...

In this period drawing, they appear to be a rounded off rectangle!

The 2nd (destroyed) car has longer front and rear fenders than the Righini car which still exists
