Updated through online information from C W Wescott.
From Reuter opus list, originally located in Zion Lutheran Church, OKC, which no longer exists. Epworth building was original location of Epworth University. Epworth building is now owned by Positive Tomorrows School for Homeless Children and is now under lease to another church. The organ is safely enclosed in the interior of the building but not in use. Visited May 18, 2015 and followed up with conversations with church and school administrators.
