Northern Telecom NTDC70AM loc E3
Northern Electric NTDC70AM. I can't find a name for this model and it doesn't seem that there are many like it around. I looks like a newer version of the Centurion and a predecessor to the Millennium. A missing link? The lower housing and the way the components are set up is very much like how a Western Electric single slot would be. Both the upper housing and vault locks are made by Northern Telecom.
