Back then, the machines weren't racist, just the people who used them as such. the Cavalier C102 was designed as described for dual sided access on a gasoline isle or a double lunch-line. Any moron can tack on any sign they want from "whites-only" / "blacks-only" or hey, you could claim it was Hitlers personal Coke machine & tack up a swastika & a "no Jews" sign while you going down that road ( gutter) of thought.
Geez!
Anyway, in any case, it's a rare machine indeed. but I'm sure RestoRick can whip one up from a pair LaCrosse LLC90's in a jiffy.
