⭕ Western Electric 555 Receiver horn driver coupled to KS-6368 Horn. As you can tell from the photos, the horn is damaged but it is complete, with metal trim and all hardware, ready for restoration or leave in vintage as found condition. The mouth of the horn measures 16 x 11 inches. The driver is a bit dusty but has no rust. There is no evidence that it has ever been disassembled or tampered with such as scratched or stressed screws or chipped finish around screws. The knurled terminal knobs and large mounting nut turn easily. On my meter the resistance of the field coil reads 4.8 Ohms and the voice coil reads 12.5 Ohms. I removed the driver from the horn to visually check the driver aperture-- what I could see (admittedly not much) appeared clean and undamaged. I dont have the expertise or equipment to test it in operation so I cant guarantee that it makes sound but all indications are that it is a good example.
