Diopter Ring Screw for 10x Viewer

This is a rare specialty screw not available anywhere. It is very expensive to make, due to it’s unique specific design. Comprised of a shafted tip which indexes into the groove of the diopter tube. It allows you to adjust the focus of the tube to the ground glass.
