That's cool.

"Waterproof canvas"... similar to a tarp. "Plastic car roofing" in
1928 I think would be asphalt emulsion, like car cement. The term
persists today as "plastic roof patching compound."

I suppose if a diagram listed "Mule-Hide roof", it means it's a canvas
roof, or a canvas roof coated with asphalt.
