The Kimball was originally tubular pneumatic. It was electrified by Fred H. Meunier in 1938 at a cost of $985.00.
The Kimball, including the facade was restored and mated to the Rodgers in 2007-08. The only tonal change was revoicing the Swell Aeoline to provide a Voix Celeste. The Kimball stops are available on the Rodgers console and are engraved in a different typeface than the Rodgers stops. The top two notes of both Kimball pedal stops are provided by the Rodgers.
At at unknown time, the Kimball was interfaced with a Rodgers "Trillium Masterpiece 968" electronic instrument. According to the website of Morel & Associates pipe organ builders of Denver, the Kimball was restored.
