Four Jaw Faceplate chuck

The C3 was supplied with a heavy 8 inch Face plate chuck with four independent jaws, these are non reversible however. The face is inscribed with circles to aid settings. There are variations of these, some also have slots in the spaces between the jaws so the jaws can be removed to turn it into a faceplate.
