More than a thousand rides were eventually built. Some of the rides produced in the 1940s and 1950s are still in operation. The earliest Tilt-A-Whirls were constructed of

Modern Tilt-A-Whirls

Modern Tilt-A-Whirls cost in excess of US$300,000 to purchase. A Tilt-A-Whirl package comes with a choice to employ either the famous domed tipkarts (which were introduced back during the 1930s), or Waltzer-style open squat podkarts having headrest bars (that option was introduced by Sellner Manufacturing in 2003). The oldest operating Tilt-A-Whirl is a 1927 model, traveling with Tom Evans United Shows in the US Midwest. Between six- and seven hundred Tilt-A-Whirls are in operation. Conneaut Lake Park in
