No idea... but I would do things with her that would make a Ron Jeremy video look like a children's show.
Peter North is a "one trick pony" really. Ron Jeremy has more acting chops and range, despite letting himself go later in his career. One of the guys in my unit in Iraq actually met Peter North at a party way back in the day - really nice guy. There's a fascinating documentary about Ron Jeremy that came out around 2002 or so. One old school porn star who really looks good for his age is Hershel Savage - he'd get plenty of tail even if it wasn't his job.
This might be her, though I found another couple of girls who also resemble the redhead. http://cosplaybeauties.tumblr.com/post/43333982738/slave-leia-christy-marie
Looks like her, but the nose is a different shape on each of them. The one at the link has a rounder, bit of a bulby nose tip. The red head's nose doesn't.
There are differences in their costumes and in their ear structures. I think they're not the same person.
Definitely not her. Red is barely able to cover her bewbies with her outfit, while yours can barely fill hers. Its possible that she's had a boob job since then, but that seems unlikely seeing as how the facebook page link your site gives is dead, and I'd think that anybody who went to the trouble to blow up their titties to better fit a slave Leia costume wouldn't kill their cheapest source of advertising.
Yeah, not her. In addition to the obvious boobage difference, there are subtle differences, too. They really don't look that similar.
