Westinghouse OV-20s in a parking lot

Here are some of these sweeties in Fullerton, CA. It is shared with the Reveres. This part of the parking lot has one Revere, the rest are OV-20s. The parking lot originally served a commerical building that presumely once housed a store, but apparently the building burned down at some point, it is gone now but the parking lots still serve other stores right around it. The clamshells are still electrically connected, but now I think every single fixture has a burned out lamp. A few years ago, one was still lit with a very dim clear mercury lamp. I hope to get those lights someday.
