Never Before Seen: This listing is for TWO (2) Vintage 1999 TYCO Toys Inc., 440-X3, DELRIN PLASTIC 25 TOOTH CROWN GEARS. The story is that TYCO Toys was sold to Mattel Co. right around 1999. At that time, TYCO had nearly developed a next generation chassis with a (blue) armature Rare Earth Magnets. The issue that arose in real life use was that, the friction torque of the chassis combined to literally melt the plastic alongside the rails ON SMALL 8' long Starter Sets! NONE of the Packaged 440-X3 HPX-3 Vehicle or sets have the Delrin blue crowns. These crown gears were probably being developed to help with the new level of torque the 440-X3 was supposed to develop.
