The Crank Handle is an item in the PC release of Mario's Time Machine. It is the handle used for one of George Washington Carver's press machines, converting peanuts into peanut oil. Carver was relying on the machine to demonstrate the value of peanuts; however, the Crank Handle is stolen by a time-traveling Bowser circa 1915, preventing the machine from functioning properly. The Crank Handle is then placed inside of Bowser's Museum, where it is exhibited alongside the other items that Bowser stole. Mario later enters the museum, takes back the Crank Handle, and travels back in time to Tuskegee to return it to its rightful owner, albeit without knowing who its rightful owner actually is. Therefore, Mario shows it to various other people around Tuskegee. Booker T. Washington incorrectly assumes that it belongs to an automobile and recommends that he talks to Henry Ford (while also giving him a Tire), while Henry Ford says that it is manufactured with "U.S. steel", but also that it does not belong to him (he also comments that he is only interested in it if he can sell it). Eventually, Mario definitely concludes that the Crank Handle belongs to Carver, and brings it to him, who immediately puts it to use on his machine.
