From the 1975 OHS Convention Handbook:
"The organ is an original installation. The 39 displa pipes are all speakers: 17 from the Open Diapason, 16 from the Dulciana, and 6 from the Octave. The Doppel Floete has double mouths from Tenor C; the Flute 4' is stopped wood to Middle B and open metal above. The Swell Violin Diapason and the AEoline both have 12 stopped wood basses; the Harmonic Flute is open wood to Tenor B and becomes harmonic open metal at Middle C. The Dolce Cornet is 12-15-17 to B 48 and 8-13-15 to the top. Boh reeds are of unusual construction. Signed by J. Schwertner of Detroit, they have dirt traps with a fine screen at the bottom of the resonators; blocks, shallots, and tongues are nickel plated."
