Hi,
I've owned a number of screen used sabers from all three films and researched these props extensively. Still have a couple sabers and a pair of my old ones that I sold through Profiles are now back in their upcoming auction. The sabers and blades were made the same for Ep.1 & 2. Threaded metal rod extending out from the resin hilt that the blade screws onto. Blades were made of aluminum, painted, and then encased in a heat shrink (like a thin, rubber saran wrap). Again, all the stuff for the first two films was the same.
They changed it up for Episode Three pretty dramatically. The blades were made in New Zealand (I think the company was called Kiwell?) out of fiberglass composite material to be lighter and stronger. This time around, the blades had the "male" threaded attachment that would screw down into the hilt. They also had fat and skinny versions of these (referred to as Hero and Stunt blades by my connection). I have a pair of both with my Ep.3 Hero Mace saber, and they are pretty different looking beside just the different thickness and heft.
Your saber in the photo is a hilt style from the first two prequels. Either the exact saber hilt you are holding in the photo, or one identical to it was offered for sale for a number of years both through Star Wares and on consignment through Screen Used. If this is the same one, and there are details that match up, then this hilt came from the set of Phantom Menance, and therefore was used for practice/stunt choreography as only the Qui-Gon, Obi-Wan, and Maul fighting sabers were seen on camera.
If you can find yourself an extra blade from either of the first two films, it would screw onto this saber with no problem. That said, production made blades from the first two films are insanely difficult to locate on their own. I have a pair of Maul blades that are the only blades I have ever seen separated from a hilt. Lots of hilts have shown up, both screen used and production made, but very few blades as most of them were destroyed on set. Very different for Episode Three. Very few hilts from the third prequel are in private hands, but a ton of carbon fiber blades made it off the set as they were more or less indestructible and a ton of extras went unused. I have a number of those.
Hope some of that helps. If I can help with anything else, feel free to email me or message me.
Troika@Me.Com. If I can put some of what I've learned over the years to use and help out some other saber collectors, I'm happy to help.
