vintage Cesco motorcycle goggles 30s vintage smoke tint lenses for flying or racing

Pre WWII vintage Cesco wide vision goggles with smoke tinted curved glass lenses. I'm not sure if these were for motor cycle riding, early automobile racing, aviation, or just working man's safety goggles.

These measure about 6" across and 2" high. These aren't perfect and show wear and age. They do have some minor damage to the plating and the chenille padding around the edges.
