I do not think it is either a Larbel or a Jedi 135, I know both did council sabers but not sure if either did that design. However the big tell for me is that I do not believe either utilized the type of matte gray coating. Usually they were the same sheen metal as the emitter or they dulled it down with anodization or glass bead blasting. At least that is how it was on their early hilts. I have a few images of the ones I owned and they do not match that coloring.
However it does look like the type offered on eBay around 2003. I think the seller was from Florida, not sure if he was a board member here or not. The hilts were done well but they did not have any black in the grooves. I picked up a couple of designs and added the black coloring, I am sure others might have done so too.
I am also fairly certain there were other offerings out their too. Luuke offered a lot of hilts over time but not sure if he ever did this model.
yup that's Oz's. I had one just like it from the same run. It wasn't an RPF run btw. There was a whole thing about getting the bead blasted finish correct, I remember. Khal, the needle bearings were done on the mace windu that Oz did, but not the adi.
I can guarantee you this is Oz's because I still have that brass emitter and plate section from my old one. we took it off to make an aayla secura saber to give to Amy Allen at a con way back when. Then I got a replacement from Oz.
I had an Oz Windu and Eeth Koth. They both had the retention collars with needle bearings. Never had an Adi, but I just assumed since it was an EpI saber that it also had the same setup. Dammit, now I want those Ep I Windu and Koth sabers back.
