The color throughout the entire body and the face has a brown spotted marble pattern. Somebody else on flickr has this receptacle (that isn't 20ampgfci) but I can't seem to find it. This is from the 50's to the 60's. If you think this is 60's, remember, grounded receptacles were considered a specialty back then when there wasn't much being manufactured so the ears and the design could or would have looked different.

Don't be fooLED, T8 IS the worst thing to do to a magnetic T12 fixture.
Lights are cool.
I know info for switches and receptacles from the 60's or before. I stopped collecting lights.
