Thanks... I did NOT know that the shroud was modified for ROTJ!
If the Barbican was used a a dueling saber in TESB, then why does this other Propstore ESB "dueling hero" exist? As a back-up? Or, was the Barbican the backup? We know that the hero ESB belt hanger (also POSSIBLY used in ROTJ, although I've heard there are no good screen shots to prove it) ended up in a Pennsylvania casino, SOMEHOW.
Do I have this correct? There were (at least) 3 Vader sabers used for TESB:
1) The casino hero
2) The current Propstore dueling hero
4) the Barbican saber, later used in ROTJ (possibly with the ESB hero as well, although still unconfirmed)
