Item DR9 - Jacobs 6A Machinist’s Chuck.

 This premium Jacobs (Hartford) chuck has a few spots of  very light pitting on the chuck shell, but will clean up well.  The three-jaw chuck has a 1/2” capacity and has a 33 taper shaft.  It is well marked on the shaft and the chuck body.  It comes with an original Jacobs key that is in fine condition.  The unit works smoothly and has been little used.  Good+
