The Edison Triumph Model D pre-dates the Edison Opera. The lightweight, freestanding horn is something of a wonder in that there is no need for a crane to support the horn.
Notice the wax cylinder being used on this instrument.
The Alva is similar to the Triumph, but has an electric motor. It was initially priced at $85 but was never a big seller. It initially played 2-minute cylinders but was updated to play the 4-minute cylinders.
