Exact item shown, Crozier (Hawthorne CA) Machine Tool 4-way tool holder - from a good friend's estate. He had one of these on his South-Bend 10, these are a great size for the SB 9 and 10 lathes and they are more solid than the quick change tool posts that you would get from anyone except Aloris - I will list another one of these and a mounting stud separately. The slot shown in the photos is to hold a cutoff blade. To use, you turn the handle about 1/2 turn and you can rotate the holder, when you get the blade into the position you want just tighten the handle back, it indexes accurately in 30 deg increments, the mounting stud holds it firmly to the cross-slide.
