Hey High Time, you are sleuth extraordinaire! Very well done. If you solve the mystery of the next thread "Farm Find", you'll be inducted into the Sherlock GA House of Rare Finds.

The one in the photo is rusty so must be something other than stainless. A chinese knockoff perhaps???!! :)

Looks like typical old stainless to me. Stainless mufflers are not entirely rust -proof.

Thanks Bill!

The example shown to me must have been modified, because I did not see the input for the outside/cold air and the and output for the cabin/warm air. I will try and get a better look at it the next time I get a chance.

What magazine did you find this in?

Thanks again.

Hi Kim,

The example in your picture doesn’t have the outer shroud installed. The shroud would have the inlet and outlet ports. I’m guessing that the gap at the top of the muffler flange allows heated air within the shroud to pass from one side (inlet) to the other side (outlet). This would maximize the overall heat output.

I found the article in my old collection of Aviation Service magazines.
