What year and model of Hudson had a heater that ran off the engine heat?
My 1923 Hudson sedan does not have a heater. It does have a blanket holders on the back of the front seat.
My guess is the driver may get some heat off the firewall which is not too thick and has a few holes. I know the first
real heaters used the exhaust to try to heat the inside later they used the heated coolant from the radiator but when?
