mystery Challenger from my past

I got my drivers license in 1978. For three years prior to that I mowed lawns and did yard work around the neighborhood to save enough money to buy my first car. I knew at age 13 that I wanted a Challenger.
So the day came when I was ready at age 16 to buy my first car. And as luck would have it a co-worker of my dad had a 1971 Dodge Challenger for sale for the price of $1600.
I remember going to look at the car with my dad. I was love at first site but over the last couple of years I always wondered what that Challenger trim level was.
So I come to you to get your ideas. Because these cars really weren't collector cars back then and I drove it everywhere. So I don't have the VIN. Just a slide, yes a slide of the car.
Here is what the car had when I bought it. And I bought it from the original owner and he said it is all stock as the day he bought it.
1971 Dodge Challenger
340 w/thermoquad(which the secondaries were working until I took it to Tune-Up masters. That day the car was transformed into a rocket)
A727 with a center console
3:23 Sure Grip
A/C
regular rear window. Not the smaller S/E one.
original paint...a dark green...not avocado color. It was a really nice green.
tan interior with a rimblow steering wheel. tan leather seats.
non rally guages.
flat non R/T hood.
dual exhaust like an R/T would have had.
No R/T badges anywhere.

So what do you think? special order? Deputy?
