Here's an interesting aftermarket accessory: ebay #222390010298
You reverse the blades in wintertime to blow warm air from under the hood out through the radiator to keep it from freezing!
I found some info by typing "The Colby Co., Lake Mills, Iowa" into Google on my phone and it brought up "American Blacksmith and Motor Shop". Clicking on that opened a page from that book that describes this fan. Sorry, I don't know how to post it here, and I could not find it on my computer, just the phone!
