M 55

Here we see an M55 phone in gray with a keyboard. On the back of the device, at the point where the cords are connected, there is white plastic and the company name is embossed on it. The handle cord is spiral. The keyboard was the same for all types of telephones. Towards the end of the 1980s, any subscriber who wished to replace the selection disc with a keyboard declared it to OTE. The keyboard was pulse.
