For sale is a Bridgeport Mill Drawbar. You will get one of four drawbars pictured. They are all used, good, with threads checked against an actual Bridgeport collet.
These are regular shaft length drawbars, but with long hex parts. This means that you could open and close collets with the quill lowered, which is very nifty. I use one of these on my mill now, for this reason.
