While this Wild Mouse may look like a Schiff Wild Mouse, this is not a known model if a Schiff Wild Mouse at all. When compared to a Schiff, the track lacks the center rail system, the cars are different and the layout is unique.
The book "Euclid Beach Park" (Arcadia Publishing; ISBN: 9780738594231) contains a picture of Shady Lake Park's Wild Mouse. The pictured Wild Mouse is identical to the Old Indiana Mad Mouse. Also given the known fact that many rides from Shady Lake Park were moved to Old Indiana, it is presumed this Wild Mouse was part of that package.
