I do not know about pre war Packards specifically. So i can only guess.

Somekind of control cable or other mechanism may have been attached to the heat riser to allow controlling it from inside of the car. Look for any extra holes in the dash or evidence of a bowden cable set up.

29-32 L29 Cord used a seperate "carb heat" control cable thusly labeled on the the dash.
