Help with AC Identification? What is it?

I have been surfing pictures in this forum of 65 Barracuda's and what has led to my a/c confussion is I see 65's with push button a/c controls in dash, only 3 small under dash vents and all pics show same compressor running dual belts. I was thinking that mine might have been a dealer installed factory kit of sorts. I will keep it in car, as I would like to believe it's a period item, just when I cruise a local hot spot, I would like to know exactly what I have.. Thank you for your help.
