That is definately a Roadblasters. Not only is the optical wheel in evidence, but that little black thing you see poking out from the front on the bottom is supposed to have the (missing) bottom rim attached to it. And if you know what you're looking for, you can see the housing tapering in at the bottom, which none of the other yoke-type controllers do.

Sadly, the Roadblasters controller is not a yoke at all- there's no y-axis guts inside the housing, and the handles are mounted to a metal rod that's welded in place- it definately does not turn.
I don't think it's good for anything other than a dedicated Roadblasters machine. Sure, you could run it through an Opti-Pac or mousehack and hook it up to MAME for 270degree games, but I'm pretty sure you'd have loss-of-callibration issues, just like the guy who built the optical yoke, or like everybody had with 720 joysticks before MAME started recoginzing the callibration wheel.
I'd get in touch with the seller and see if he's got the appropriate controller somewhere, because that one won't work for Hydra, which is clearly what he was selling it as.
If you do end up with it, you can probably still make your money back. The Hydra boards ought to be worth something by themselves, and you could probably sell the Starwars grips, triggers, thumb buttons, and switches all separately to guys trying to rebuild SW yokes.
Good luck!
