Worked on a '39 Dodge with one of these, but doubt it's a Chrysler Corp. part. Possibly a Ha Dees ???
Most likely one of the many brands of aftermarket accessory available in the '30s and '40s. Few cars or trucks built before WWII had a factory installed heater. Even the "correct" heater for a particular make and model was a dealer installed option. Most optional equipment back then was dealer-installed. Most people bought one of the many brands of aftermarket heaters instead of buying one from the car dealer. The heater in my truck is a Hot Wave brand. If you look at unrestored original cars of the '30s and '40s and cars of that vintage that have been sitting in junkyards a long timd. you will find more with one of the many brands of aftermarket heaters than you will with the correct original heater.
