Gloggomobil

The wooden barrel is spun by means of a hand-crank on the side. Small pegs are inserted into pre-drilled holes in the barrel to determine what note plays and when. The music plays on a small-scale metallophone or Glockenspiel (like a xylophone but with metal tuned bars rather than wood). Where you see more than one peg on a line, the instrument will play a chord. It looks like it comes with pair of mallets for composing or non-automated playing.
