The barrel is original and production used, though not screen used. It was one of several used to float the special effects platforms. They were all black. The special effects crew took five of them and painted them yellow to represent the shark, since most of the time the mechanical sharks were not working. I purchased two of them from Lynn and Susan Murphy of Martha’s Vinyard. I painted them yellow to match the ones seen on film. TNow that is a cool collection, where did you find the barrel?
