That looks like the same solenoid and starter as used on the 356 thru 50. One of the screw terminals is connected to ground and the other to voltage. Just how the circuitry was routed by Packard depends on the car model -- on some the operator's starter switch is in the ground leg. Others, the switch is in the hot side. Both methods did have the ground actually go thru the generator with the hot side either direct off battery or thru ign sw.
There is a relay inside the rectangular enclosure which does actually bring in the solenoid. Here is the schematic and info for the Autolite version from an old Motors Manual. As mentioned, Packard did it their way so ignore the drawn ground in the schematic other than it means one terminal is ground and the other voltage. The two small screw terminals on the solenoid are the one directly connected to the relay coil.
