I'm necro posting a bit to add some corrections to the record, for anyone new coming looking for info.
The Barbican saber we now know is the first attempt at a Vader ANH stunt saber. Ended up having to re-use Luke's, but it worked out in the end.
Halliwax, is this grenade all black? Do you know anything about B&W photos? I know blue shows up dark, red shows up lighter, etc. It ould explain the V2's paint scheme, and why only the upper (covered) part of Obi's saber is brass.
Also, the bottom ridge is not thick
Anakin Starkiller I remember that thread about the tunisia saber....
Wanted to note that there's a copy of the Energizer saber there, behind the Barbican and the Icons Obi Wan. (If the original is still with Don Bies it's a copy). The emitter is put on sideways, that black dot facing us was in the front of the saber, so the black top must be rotated 90˚. Maybe it fell off, like when AL ROKER FLUNG THE FLASH HIDER OFF THE HOTH BLASTER IN 09.. Whew...
Anyway.
