C2 -1966 License Plate Light Assembly

[Robert T.]

"Restoring" my license plate light assy. Like the JM references, I see a lot of "dull silver" paint on the outside of the housing. On the back side, I don't see a trace. So...I assume one of two conditions;

1. Every spec of silver paint has come off of the backside.
2. The backside was never painted

Can someone confirm on the originals if they were painted on one or both sides?

Thanks.

Bob
