This practice instrument for the Music Building on the Bloomington campus of Indiana University was constructed with the same console dimensions as Opus 135 in nearby Auer Hall. Students at the Jacobs School of Music may prepare their work on this organ, easing scheduling demands on the much sought after larger instrument.

The Principal 8', Spire Flute 8', Bourdon 8', and Flute 4' are available on Manuals II and III on an alternating basis, and may be used simultaneously on Manual I, which is permanently coupled. The Bourdon 16' is an independent Pedal stop and the Spire Flute 8' is borrowed to the Pedal from the Manuals.
