The "horn" is the intake for a heater. It ducts air over the hot exhaust manifold into the car for heat. Usually there is a hole cut in the firewall behind the manifold heater to pass the heat and it doesn't look like your car has the hole cut. This was an aftermarket accessory for the Model A since they did not come from the factory with a heater. The line coming off the intake manifold supplies vacuum pressure to run the windshield wiper.

On the choke rod you should have a long spring that pushes the grommet against the firewall. Your's looks to be in the middle of the rod.
