Here is a photo of the Stromberg Carlson version along with a schematic attached, for the Western Electric version.

B.  407B (MD) and 407C KTUs (Dial Intercom, 10-Code Selector Circuit)

2.03 The 407-type KTUs (Fig. 5 and 6) are 8-inch, 80-contact units for use with the dial selective intercom circuits. They provide the following basic operating features:

   
• Maximum of 10 station codes (0-9)
• Busy lamp at all stations
• Adjustable single spurt signaling (0.5 to 2.5 seconds) by adjusting timing resistor
• Rotary dial selection.

The 407C KTU replaces the 407B KTU (MD) on a plug-compatible basis.
