Trav-A-Dial indicator - this worked by friction against a ground surface

Heidenhain Optical Reader. These units could be fitted in place of the dial indicators. The position was read from a combination of a magnified image of a precision ruler marked in mm and a direct-reading drum graduated in intervals of 0.01 mm

Universal Dividing Head equipped for direct dividing (by an indexing plunger into a gear) and quick workpiece clamping by a lever.  The plain tailstock shown is also equipped for quick clamping
