NYNEX Tamura Change Card Phone

Model DC5-US-N made by Tamura for NYNEX. This is a prepaid card, coinless public phone. The lock is a Medico coded BAAA1. The prepaid cards were specifically for use in these phones. This is the later of 2 types that were put into service. The earlier ones were likely used for field trials. Some changes these had from the first model is that the shape of the phone and the mounting pattern is identical to standard payphones and they were locked with a similar lock to a payphone and utilized rails that were released with a T key. The yellow payphones were in service in New York City for a few years, they were a flop and were removed replaced with updated smart standard payphones.
