Updated through online information from Scot Huntington. -- The organ cost $14,560.00 and was contracted to be delivered on April 1, 1926. This was the first organ in this building, which replaced a previous building at a different location housing an 1891 Wm. Johnson & Son instrument [Op. 755]. Pipework from the Johnson was used in this mechanically new organ. The contract specified the builder had complete use of the building for a period of not less than four weeks, and that for two weeks, the builder had use of the building completely free from noise, "so that voicing and tone-regulating may be done without interference". The contract specified that metal pipework should be of not less than 45% tin, except the Vd'O, Celeste, and Keraulophon were to be 70% tin with 6 zinc basses; wood pipes of pine and poplar. The reused Johnson pipes were to be revoiced on the new pressure and pitch (A440), mutilated tops and tuning slots repaired, and old wood pipes to receive two coats of orange shellac after cleaning and renovation. The blower was to be a 5 h.p. Kinetic, with a belt-driven DC generator. The description of the console stop control is open to interpretation: "oblique-faced knobs set in terraces". The dedication recital was played by Henry Seibert of New York City, on Tuesday, January 4, 1927.

The organ was substantially rebuilt into an essentially new organ by the Schlicker Organ Co. of Buffalo, New York, in the mid-1960s. The Moller chests and a significant number of Moller ranks, including most if not all the surviving Johnson pipework was reused. The walnut Moller façade, designed by the church's architect, [W.L. Mayer, 212 Charles St., Mt. Olive Station, Pittsburgh], and "gold-bronze" facade pipes of the Moller 16' Double Open Diapason were reused by Schlicker.
