It is NOT asbestos, it's more then likely cardboard of a type, similar to fish paper, treated to render it heat resistant. In any even Philco didn't use asbestos in it's models during the 1930s, they either used nothing or a steel cover over the bottom of the chassis. Asbestos is a white or grey color with a rough texture, not smooth.
