From what I can see, all 3-4 cars mentioned are air-cooled and have inlets at the rear.

Porsche 356's have cabin ventilation, although as with the later 911 it's not very good.

The Volkhart V2 Sagitta (1947) has inlets at the front, could be for the cabin ventilation, front brake cooling, horn, or a front mounted oil cooler, I do not know for sure but if I were to guess it would be cabin ventilation (actually looks like a fan). Cracking a window open I suppose would be an option.

I think that what is pictured is the horn.Not sure.
