Matey, my Star Wars Trilogy is folded up on a storage rack in my garage so unfortunately i cant help, otherwise i would jump on it and help straight away.
Go thru the "your collection" segment of the forum, and see who else owns a Star Wars Trilogy, or u can pop into one of the dealers, or get someone who is going into a dealer to take some photos for you. Also, there are some videos on youtube of some machines if that helps, but visiting a dealer with some photos is the answer i think.
