That's interesting. I had two 6-volt window defrosters like that I used on a few of my old cars. Even had tire chains for one of my Model A's. But they handled pretty well with those skinny tires without. Later I had one of those side window air coolers for my 49 Dodge. It was my uncles when he went out west. Who'd a thunk that junk would be worth anything now?
