My theory is that it's a straight telecine from the original film. When it was done, who knows. I believe the EOD crawl is original as well. I remember zombie had some info on that way back when. I can't remember what I found when I compared the two, but the GOUT crawl lines up exactly with the '77 telecine - stars, wobble and all.

Edit: I don't really remember what Boris did to back up his theory, but I do remember that most of us were convinced it was a generated crawl - myself included. But I did my own research and lined up the GOUT crawl with my copy of the old crappy '77 telecine DVD. When I squished the GOUT to match the aspect ratio of the old VHS transfer, they wobbled exactly the same, and specks of dust and scratches in the film were in the same place.
