When Kransco sold Wham-O to Mattel, all the old Frisbee guys like Stork Roddick left the company. Some new golf discs came out, which went away from the traditional Frisbee method of numbering the molds. This one was called the Voyager.
It's some sort of small-diameter driver. There was also a Voyager II. I really have no idea what the difference between the two were. An Internet search said the Voyager was made from the Polaris LS mold and the Voyager II was from the Polaris LF mold, but who knows?
