If my wife's feet are kept warm then Mama's happy and when Mama's happy I get to keep happy. The exhaust manifold heater works good enough for this....
I googled the Internet on the Model A exhaust manifold heaters and found this very well done article in the Wichita A's newsletter from last year.

Now I am curious as to how many manifold heaters were actually offered back in the day. I have started a collection of photos of what I could find so far.
