This is from a relative’s estate and I do not know the brand. 3 metal lathe 4-way tool post holder with quick change lever. This works perfectly and is in very nice shape as shown. It is missing one Allen head set screw to mount a tool post as seen in the last picture. Two sides are complete with tool inserts, one only has the moon section (and a wood block to keep from losing it), and the last side is empty. Exact item pictured and the top of marked STC2. LOOK AT THE MANY PICTURES!
