Great.
"Berlina" only means "saloon" and it's a quite general definition. "Panoramica" at that time was often used to underline the large windows area: "panorama" in Italian means landscape. Only later panoramica got the same meaning of station-wagon.
Just to complete the info, my source is a feature on Auto Italiana magazine, talking about the 1948 model (only with minor differences in the trims).
Perhaps may you post me this one in bigger size by PM?
