Hi Jason
Yes, it had at least one motor with pulleys and belts in the back. A motor-operated bellows produces the air for the organ pipes. I only saw wooden, reed type organ pipes behind the swell shutters. I'm not sure if the xylophone, drums and snares are operated by vacuum or otherwise. And then it is operated by paper rolls, just like player pianos are. John, the owner, mentioned that this was a top of the line model because it is capable of playing a roll while simultaneously rewinding the previous roll. In case you aren't familiar with how the roll works... First, the paper glides over a bar with holes. When perforations in the paper match up with one of the holes in the bar, it creates a vacuum which in turn causes the machine to play a chord or note. The entire thing is very mechanical, which makes sense, because after all that was the machine age.
