Looks like you have a v1 Bib Fortuna Staff if you were cross referencing against TIG.
Can not tell for certain from the pics regarding the imperial blaster or Jawa Blaster, though they look too shiny and smooth to be the real thing - would need clearer shots but tend to agree that it's unlikely to be an original if it's been recarded.
I would have said bib fortuna looks real if it does not sink. But with all this new repro stuff then I am not sure about so much anymore. Does any of you know if the new repro bib fortuna staffs floats ?
