Schlicker organ relocated to Acme from St. Paul's Lutheran, Monessen. Instrument originally installed in St. Mark's Evangelical Lutheran Church in Monessen, which closed in the 1990s. As part of a merger between parishes, the instrument was moved to St Paul's when St. Mark's closed.
Relocated to the Acme Organ Institute in 2019. A Pedal 16' Principal extension (12 pipes) has been added, and the 4' Quintadena removed from the pedal specification.
