It is my understanding that prior to air conditioning the vents in clerestory roofs somehow provided air flow into the car.  Does anyone know how they operated.  Also, some pictures show what appear to be screens over the vents (perhaps to exclude cinders, birds and other unwanted items from entering the car).Any and all information will be appreciated,Jim Cochran
