Deluxe cab? There is none! Truck cabs during these early years all came the same from the factory. Accessories were dealer installed. You picked the factory installed exterior color and transmission. (3 or 4 speed) The dealership added the requested extras such as heater, right inside sun visor, right outside mirror arm, etc.
This changed on the Advance Design Cabs during 1947-55. The pickup had a deluxe cab because it was given factory rear corner windows, a right side sun visor, and door and windshield stainless trim.
