I've fully restored a 1980's Bell System Payphone, built by Western Electric (sometimes known as "The Fortress"). It's like brand new, but has a small (like 1 cm in lenth, 1 mm deep) ding in the back, which you can't see unless you look for it. Since it is on the back, no one will see it if mounted, and the head set has some dings on it. (Replacement headsets cost $10) However the enclousure has been sandblasted and got a new coat of powdercoat paint.
This payphone WILL work with your home phone line, even with all the payphone parts inside. I did NOT ripped out the insides and replace with with the guts of a normal home phone. This has all of the parts intact and inside. The coin return slot even says something like "Bell system. Built by Western Electric"
This phone is the real deal, the standard payphone.
These retailed for about $1500 new, and I am looking to get $300 + $50 shipping for it. It comes with both keys and T key.
