From our regular Curbside Classic Clues, to a recent headline hunt for This American Life, TTAC’s Best and Brightest have proven again and again that they’re the internet’s go-to resource for crowdsourced identification of the most obscure elements of automotive esoterica. In fact, I’m beginning to wonder if it’s even possible to stump some of you guys. Which is why I sat up and took notice of Hemmings Motor News’s Twitter appeal for help identifying this obscure, coachbuilt baby, posted at Coachbuilt.com. I figure this is as good a shot as I’ll ever have at pushing the limits of your collective automotive knowledge. Or, proverbially, not.
