One of the guys at PaleoPlanet or Leatherwall did the wood bows she uses.  He posted briefly on here when the last film came out...long after the gag-order part of his contract had expired.  
He posted pics before they removed the horsehair flourishes and other fancy-pants stuff, was a pretty cool looking bow.  Anyone remember who he is?  I remember he seemed to be pretty nonchalant about it, like it was just another bow job.
