• BSP for this phone

This is a very rare 2 line set designed to work with a speakerphone and/or key system.
The set has a lable on the bottom: Turn A-Round 906 W. Erie, (month unreadable) 1975.
The housing has been modified to fit the unusual cord by adding a set of rounded, 123A inserts that are designed to allow larger cables which must be connected inside the phone to pass through housings that were modified or built for modular plugs.
