A black, bakelite call unit meter used to calculate telephone charges. The meter has two analogue indicator panels (relays). The left meter, in a grey, plastic frame, calculates the units of each individual telephone call and has a white button that resets and restarts the counting of telephone units. The right meter, also in a grey, plastic frame, calculates the overall telephone units consumed in all telephone calls. Between the two meters there is a white key that resets the call unit meter. The base is plastic and white.
