I have 4 mid-60s general electric "municipal style intercoms." Model number - 4EC28A1. My electronics technician is restoring 3 of them for me. He tells me he really needs a wiring schematic to thoroughly complete the restorations. We aren't having any luck finding the diagram online. Might someone be able to help us locate the schematic? Thanks

You might check this closed sale on ebay. The item sounds like a General Electric RC4 Progress Line Remote Control for a radio.
