    No idea, but let's compose a piece of music for it!

    Early audio recorder/player ?
  • Ross said:
    Funny that 1923–1929 is well before the invention of the Leslie speaker, which this definitely resembles.
  • Ross said:
    The nameplate on the speaker horn says Western Electric and maybe model 518-W? If so, that was a domestic radio speaker and probably wouldn't deliver siren-level volume. The question remains what it is doing on the spinning rig—it looks like there are slip rings to make the electrical connection while spinning. Radio special effects?
