I was in Seattle during my spring break and I went to the Sci-fi museum. It was neat to see lots of the stuff but I was wondering if anyone knew anything about the authenticity of the items? Mostly The two apparently "screen used" lightsabers and the stunt Vader lid both from TESB. It was neat to see them but the lightsabers seemed a bit fishey. The Vader was a graflex with out the bunny ears, looked slightly RotJ but the part under the flat black part that goes around just under where the bunny ears would be wasnt the same as the ball catch I'm used to seeing. As well it had a graflex clamp that was wrapped in black foam (it looked old) and a circuit board. The grips also had four small black rivits holding them down. The Luke still had the beer tab and it didn't ave anything inside the clamp (where the bubbles would be). As well I don't think it had rivets holding them down.
A lot of neat stuff there, everyone who's in the region should check it out!
