Here in TX the 2 most common ways of enclosing the panels were to mount the meter and panel under the porch roof near the ceiling, sometimes the meter would be mounted outside with the panel under the roof. (common with screen porches) The other common mount was the meter was surface mounted on the side of the house with the panel mounted below, bolted to the back side of the inside wall.(shiplap) A wood or plywood door covered access to the panel. If you opened the door, you could see the inside of the wall cavity making fishing wires easy. Many pre war houses had a 2 ckt safety switch with 2 30a ckts serving 2 14 ga K&T common neutral ckts.
