Asbestos heat shields in the first Trans Oceanic's and other early radios

I posted this as a reply to a thread but it's important enough to have it's own thread and maybe should be a sticky.

Be careful there is an asbestos heat shield in the first Trans Oceanic's. I use a respirator and soak the heat shield in polyurethane to encase the asbestos the remove and discard it. Other early radios also have asbestos in them be.
