While searching the Web I came across the site for Orange Coast Piano.
I found it very interesting because they have included photos of various
automatic musical instruments for sale. I don't know if they are asking
fair prices. Check it out at:

Some of the items displayed there:

  Reproduco Player Pipe Organ
  Seeburg Style "MO" Celesta Instrumentation 88-note piano
  15-1/2" Polyphon Table Top Disc Player Musicbox, circa 1880
  Model "Y" Orchestrelle, built in 1904
  Niagara Military Band Organ, circa 1908
  Shaeffer and Sons Player Piano
  Holcomb and Hoke Popcorn Machine, circa 1910
  Scope-a-Tone, 1950s
