On the upper surface made of hard rubber there are four brass columns with terminal screws. Opposite terminals are connected by jumper wires according to the scheme illustrated in exhibit 23. Below the quadrants section there is visible the mirror whose rotation causes the reflections intrinsic in the Poggendorf method of readout.(exhibit 371).
