You're saying you agree with me, but it sounds like you're actually agreeing with the opposition!
There's no dispute that Willys designed the slat grille. What the Ford jeep peeps like to say - and note that none of this is deadly serious, but just one of the umpteenth things that Willys and Ford guys like to fight about - is that the grille that the modern Jeep logo represents was created by Ford "running with it." I argue that's hogwash. There is no dispute that Ford introduced the pressed steel grille, to cut production costs, but it simply follows the shape and distinctive features of the front of the vehicle that Willys MB created. If the idea to stamp it out of pressed steel had come from the Quartermaster Corps, and given to Willys to execute, there is zero doubt it would've looked exactly the same. It's the frontal profile of the vehicle and the location of the headlamps that gives the grille its now iconic appearance.
I will post the article later. We have enough Jeep guys and guys with enough ancillary interest.
