I'm pretty sure it's a belt drive. I could be wrong, but looking at the console, (and this involved me using a magnifying glass) I detected that the control panel part of the console was raised just a little above the rest of the console along the top, and that the face of the panel had a little bit of a silvery glint. This matches a model that was popular between 1972, and 1975. Again my assessment may be faulty, as I have low vision. I hope somebody gets them and gives them a home.
Have a good one,
James
