Tracks and motors with gearboxes that were used in the 21st Century Toys Abrams tank. These are extra parts from the mfr and were not "liberated" from a complete tank. This includes FOUR left side motors, sprockets and gearboxes. To use for both sides, a unit can be inverted for a right hand installation. Includes two track looks, each approximately 60" long and 3" wide. These parts can be used for custom tanks. The gearbox is also the same as used in the 1/6 scale Stuart tank. Thank you for looking
