Very nice - hard to find direct reading graduated large diameter collar upgrade for the cross slide compound rest top of a South Bend 9" or 10K lathe. The direct reading graduated large diameter collar dial is sharp and legible, reads to 200. Each indicator represents .0005" movement. Screw threads are in fine order.
