This is a Ericofon 600 sometimes called a cobra phone, it's actually dark brown but the digital camera decided that it would look better almost black. This one is made for the Dutch phone company "PTT". It was only supplied in three colours, a dark deep Red (a deeper red than in other European country's) White and Brown. The phone has a black base plate which is only found on this model. Inside it has a buzzer for the ringer, not all European Ericofons have a ringer or buzzer fitted.
