The sports car accessory company AMCO made these grille aperture guards for E-type Jaguars in the 1960s and 1970s. This one has been rechromed and not installed. It is excellent, but the bars are not perfectly straight, which is hard to see in the pictures.
It is not an obvious bend but you can see it on close examination. I did not see it when I bought the item myself!
It would be excellent on a driver, and very few people would ever notice the distortion.
