Identified through on-line information from James R. Stettner. -- This was the electrification of an existing Wm. A. Johnson tracker, Op. 254, 1868. However, that presents a puzzle. Johnson's opus 254 is listed for an unnamed Episcopal church in Catasauqua. It is not known if the organ was transplanted at some point; if it was reassigned to a different conrgegation; or if the Presbyterians took over the former Episcopal edifice. The Mudler-Hunter received new pipe additions and a new console in 1972 and 1994. The organ is presently 18 ranks.
