I ain't a Ford man however...........

Here`s a question for all the older guys 70s +.
I`ve searched and can`t find any conclusive answer.
I`ve considered the teardrop scoops to be seen first on the thunderbolts as really an extractor. Talking to rodders 10 yrs my senior say they were real popular and was seen on everything back in the day.
I`ll still say they are/were a Ford scoop.
What say you?
