As part of our restoration of an 1875 Henry Erben organ, electrified in 1923, we obtained a 3-manual E. M. Skinner console that had been rehabbed and converted into a "Hauptwerk" MIDI organ. Part of that rehab included new stops. As you can see in the photos, these have been wired with modern PVC telecommunications cable and have spark-suppression diodes. Can anyone ID the manufacturer? Perhaps the exterior casing or the label is unique to a particular maker? Thanks.
