Touch-Tone Pay phones
While most only think of the WE
fortress pay phone as the only Touch-Tone models, some early three
slotters were converted to touch tone service before they were
obsoleted by the more rugged Fortress.
A 1965 10 button conversion
Another Three slot conversion.
A chrome version
A WE Credit Card phone, no coins.
I do have a WE Fortress ,full NYNEX
version. I will post when I get a new camera.
