Deluxe Sport Roadster?

[Stretch Cab]

My father gave me the car in the picture. He always called it a Deluxe Sport Roadster. Was there ever an official designation of "Sport" in any of the "A" body styles. If not about when did this extra name start to be used. My mother gave him the car for his birthday in about 1971 and I wonder if this is a 70's era identification add on?
