Northern Electric Centurion

Northern Electric Centurion in rotary. This is a post pay model, so there is no coin relay. The handset is embossed with NT (Northern Telecom). These phones are made of metal and have plastic covers. They were made touch tone and rotary. The cover would be different if the phone was touch tone. These were also made with different color covers with matching handsets. Note the special T key that helps get the cover off, a regular T key wouldn't work due to the latch being very close to the wall.
