Vintage Hardinge Collet Drawbar (for lathe or BB2V, BB4 milling machine)

For sale is a Hardinge? Drawbar for lathe or milling machine? This drawbar does not have any markings and the collet does not either so there is no way to identify. I have included many photos with different dimensions in case that will help identify this drawbar.

I would appreciate if anyone has any information on this. Overall, it is in good shape. Includes Jacobs Model 633C drill chuck. The collet thread size appears to be 13/16" - 20" TPI.
