It is a 1933ish 35A dynamo. One wire is the Field and one the output, fathomable by removing hte cover. The output goes dirct to a large brush. The coiled resistor if inatct feeds a reduced voltage to the the field for Summer. For Winter, lights on etc, the dashboard switch directly links the two wires, assuming the field wire is continuous to that point.
Apart from brief testing the dyn must not be run without the external connection (eventually to battery thru operated cutout)
