Verizon 1D Magestic Theater loc LR5
Verizon, Western Electric 1D which started out as a 1C, was in converted in place back in the 70s? I tested it and the loud button still works, most of the phones I've come across have them disconnected because the board would fail and take the phone down. It came from the Magestic Theater back in the 1990s.
