Dorian SD50DA DA Wedge Style Quick Change Lathe Tool Post Bare No T-Nut or Stud. This is a bare DA quick change tool post, comes just as shown with nothing else other than the shop-made lever. Please take a look at the pictures to judge the condition for yourself. Only cosmetic issue I see is some old rust pitting on the front face of the unit which does not affect anything. I’ve verified that it works and holds a compatible DA tool holder securely.
