I recently bought a Jackson guitar from a friend of mine (and he bought it used as well) It's a V shaped body but it's not the King V. It has 24 frets and the serial on the back is NHJ0903288. I want to know the model of it in case anyone asks me, I don't want to be the guy who says "hurrrr it's a Jackson Flying V"
Here's a picture of it.

(Ive asked one person and they say it's a JRR4, but id like some confirmation on that since he's not what you'd call a "guitar wiz"

Thank you in advance.
