Seventh version of Kennywood's 1901 Old Mill ride.
This period of the 1901 Old Mill in Kennywood is least described. It is known that the ride was rebuilt and enlarged for the 1926 season, receiving a new façade and a new queue line that would remain intact until 2004. After that, some changes to the ride during the 1950s are known, such as the addition of the mechanical Monkey Band over the loading platform. The ride received a major update in 1957, resulting in yet another version of the Old Mill.
