Machinist Lathe CXA Quick Change Tool Post With Toolholders 250-301/&302 Posted on December 19, 2023 by admin in machinist I don’t see a makers mark on it. Appears to be USA made, I believe, and think it’s CXA. It’s also missing the knob on the handle. See all pictures for the best description. Check out my other listings as well. Thank you for looking. admin admin wrote 4748 posts
