Hi Frank,




The colored wires are the outputs.
Under the brown phenolic you can see the 12 tone arms (different length, for different tones). And under the tone arms there is the single relay coil (yellow cylinder).

The tone arms are very similar to the ones in mechanical music box (rotating drum with pins)
