The chassis is steel, thus the rust. I know some chassis have a cadmium coating which is toxic when inhaled or ingested but I don't know what Philco used. If you do a wet strip with naval jelly or EvapoRust (see Bob Andersen's thread: http://philcoradio.com/phorum/showthread...8#pid52748 ) inhalation is less of an issue. If you sand or wire brush then dust mask or respirator is needed. (I wear a dust mask any time I sand anything).
