The coin controller I built only works on the C series and 3 slot ground start pre-pay phones. I have 2 phones I would like to get working. A 1C1 with D innards. and a 2C2 also with D innards. Would be willing to trade for them as the D innards work well on regular loop start phone lines.
Interesting project.
Could you please tell us about your controller, how it works, chematics etc.
Thank you.

What I will say at this point is the phone has to be original with no modifications from the way they were delivered from Western Electric.
The 1C was a drop in replacement for the 3 slot phones. When the installer went out to "upgrade" the booth all he had to do was swap out the phone.
Both of these phones work off the same controller.
