2 sets starrett 190 jack screws machinist tool 2 1/4"
Here are 2 sets of Starrett 190 jack screws. There are two jacks (one is missing the flat top piece), two large extensions, two small extensions, two extensions bases (for use against a cylindrical form), and two pointed extension bases, and two auxilary pointed screws. One set has the original box, but the other is in a National Twist Drill Co box.
These are used, they have some light rust. There are tiny spots of pitting here and there. One of the jacks is missing the flat top piece. I assume all parts are Starrett, but only the large bases are marked. The Starrett box is in pretty rough shape.
