Bridgeport CNC R2E4, Belt & Pullies

Just bought a BP for $300 on Ebay. The previous owner purchased it
from a trade school. They needed the control system as spare parts for
their other BP.

What belts and pulleys are used on X, Y, and Z axis. The pulleys
around the quill and X axis are there, but the drive pulleys are gone.

Any help or just point me in the right direction, please.
