The Geigen Principal 8' has open wood basses with inverted mouths; the Swell 8' strings share an octave of stopped metal pipes. The bottom octave of the Flauto Harmonique 4' is of open wood melodias; the tenor octave is open metal; the stop is harmonic from MC. The Violoncello 8' has inverted mouths. The organ was renovated by Carroll Hanson of Iowa City in 1972. The wind system is not original, having been replaced at the time of the renovation."
