To celebrate 20th Century Fox's 75th Anniversary, the London Film Museum had a special exhibit of costumes, models and props from many of the studio's films including this collection of lightsabers from Star Wars, including those used by Jedi Knight and Sith Lord alike, Obi-Wan Kenobi, Luke Skywalker and Darth Vader.

Princess Leia Star Wars blaster
In addition to these lightsabers, on a recent visit to Las Vegas I chanced upon this gun prop at the Planet Hollywood Cafe which claims to be Princess Leia's blaster from Star Wars: Episode IV - A New Hope used by Carrie Fisher (although interestingly stamped on its side it says 'Made in the U.S.S.R.').
