The three shark models initially built for the film - all dubbed "Bruce" after Speilberg's lawyer, Bruce Ramer - were said to have been destroyed after filming.
However, NPR reporter Cory Turner recently learned of the existence of a scaled-down fourth shark also made for the film. The smaller model was featured at Universal Studios Theme Park for 15 years, but was dumped in an unknown location after it was taken down from display in 1990.
It has finally been found by Turner at a junkyard in Los Angeles' Sun Valley area.
Roy Arbogast, a member of the special effects crew on Jaws, says, "It's the real one. It's just kinda nice to see it again after 25 or 30 years. It's amazing that it's still here."
