I can't read the model number in your picture. Is it possibly a DF16 model Daytona? If so, the same drill press was marketed for a pretty long time and with a few other brand labels on it. I had a used one for a while but sold it for $50 during one of my moves. One of the other identical brands may have a parts stock site.
Model number is kind of generic, as it probably means (D)rill press, (F)loor model, (16) speed, so someone else may use the same model number for a different machine. One brand of DF16 may, or may not be, identical to yours.
That's the exact same drill press as my old Craftsman, I know who built it for Craftsman now.
Here is the Craftsman manual with some part numbers, don't know if it will help you much because of the shape
Sears is in:
Had trouble sizing scans, you should be able to see something now.
