I saw that new Sideshow Toys Mythos Obi Wan figure (I thought this was a statue series?) and he has Anakin and Qui Gon's lightsabers attached to his pack. At first I was thinking Obi Wan probably had Qui Gon's lightsaber in his room at the temple and wouldn't have had time to get it. However since they went back to the temple post Order 66, I'd guess he'd have time to get it, and would want to retrieve it. So does that mean that Luke would have Qui Gon's lightsaber in the OT and beyond? I doubt if Obi Wan left him a book with information on Jedi stuff (don't know if that is canon or not), which is supposedly how Luke knows to build a lightsaber, that Luke would have left that lightsaber at Obi Wan's house.
