(Please refer to my other Edison Home page for the history of this popular phonograph.) What makes this early Edison Home particularly unusual is the accessory Edison "Duplex" reproducer. The curious invention features a reproducer with the diaphragm mounted a couple of inches above the stylus, with a long wire link. A separate L-shaped tube extends from the side to connect to a second horn, pulling sound from both sides of the glass diaphragm. The Duplex reproducer sold for a pricey $9 in 1897 and was not popular. Only five are known to exist today.
