Sounds, and looks like what was termed an "inside metal roof" where the roof was sheet metal panels fitted between the carlines. The visual clue is the rather prominent nuts on the fascia, which is spaced away from the car siding to let the water drain out. The wood outer surface was only to protect the sheet metal panels from foot traffic. Chicago-Cleveland was one manufacturer.
