This is a International Harvester Pinion Gear. The number 200 is written on the bag so it may fit a model 200 but we are not certain. It is a 33 tooth gear. New Old Stock Part. Part listed replaces part numbers and fits machines listed, however there can be other part numbers depending on when the machine was built. Is in the lower 48 states. It’s not always best or cheapest to pack in large box. Please let us know when you get it. Street address required for UPS.
