I've never thought it was a mistake, I've thought maybe it was an early production or maybe a car/grille that was sold overseas. I'm familiar with plastic injection dies, my dad was a tool and die welder for 40 years. If somebody cut and glued the pony in they did a flawless job, but from close inspection I'm almost certain it was made this way. But it's funny that no one else has ever seen one. Maybe I'm wrong, I dunno. This weekend ill pull the old grille off the shelf and take some good pictures of it.
