The setting knobs that are used for selecting any number from 1 – 9. The counting dials that shows the results and the counter position. The clearing lever that by rotation can clear the dials. The reversing lever with its two working positions. The special plastic shock-resistant carrying case, which opened with a clockwise twist.
