tbm3fan posted a couple of shots of this survivor, which is showing the ravages of time. Looks like some red tape or plastic wrap is being employed on the roof, and some duct tape to keep the vinyl half-roof from flapping in the wind to badly. But here it, still chugging along. And no obvious rust. It was shot at the former NAS Alameda, in the Bay Area.
Here’s another view. I have a hard time pinning the exact year of these down, so please help yourself.
