Not really. If you check IMDb, I think they'll all say 2.35:1, because that was the OAR of the movie, but if you do the math on a capture, it isn't always right.

... and whether any of the LD or VHS releases contain the original theatre cropping?

Part of my point is that "original theatrical cropping" is a bit nebulous. It can (and does) vary a bit from theatre to theatre. When a movie is transferred to video (telecined or scanned), there's always a little operator preference involved in the exact framing. Unless it's completely botched (like some of the early Back to the Future DVDs, or in the case of the 'incredible shrinking aspect ratio' of some earlier Star Wars releases), you really can't complain. Film is film, and you always lose just a bit when you project or print it.

In the case of the differences in framing between some PAL and NTSC transfers of Star Wars films, I think it really doesn't matter much which framing is used. They're both faithful to the original theatrical presentation.
