Hey Luke,
Nice project you have going here. I'll follow your progress with great interest. I'll just let you in on a little secret. As you may know I'm into graflex flashguns to become lightsabers and even though screen-used props may look very cool on the screen ... many a time they look crap in reality ... as long as they look excellent on the screen from a certain point of view ... towards camera. That being said I found it very much more gratefying to make my own ANH lightsaber with 'found' vintage parts, then just throwing a bunch of $$$ towards say Master Replica's or even more $$$ towards a so-called screen-used ANH/ESB lightsaber sold by Gary Kurtz in an auction, which from my point of view wasn't even accurate to the many pictures of said lightsaber even if it did have screen-time.
So my point is that in the end you'll be much happier with having accomplished the task that lies ahead ... putting this time-turner together with all the pieces that you have gathered uptil now ... then tracking this person down who just put a lot of dough on the table and be done with it ... he just may have put it in one of those goblin's vault to gather dust and never see the light of day ... ever (sorry just playing devil's advocate :lol) Hang in there brother ... you clearly will succeed when you put your mind to it!
