Rare Western Electric 1510F 2-Line Ten Button Touch-Tone phone from 1967, with original 4-prong plug.  This was a very rare variant of the 1500 / 1500D, and features the ULTRA-RARE 25W3 touch-tone dial.  This dial could actually be upgraded out in the field to make it a 2500F.  Look at the fifth picture closely and you'll see that the sextile (*) and octothorpe (#) positions were roughed in, but never enabled later on.  The other dials from the 10-button era (the "A", "B", and "Y") could not be changed to 2500s.

I wired line 1 to the red/green pair, and line 2 to black and yellow.  Ringer only rings on line 1 -- this is normal.  Touch-tone dial works perfectly and transmitter/receiver sound is crystal clear.  Wired for 2-line pickup and signaling (to 5 and 6 on terminal strip).  Can also be rewired for extension cutoff -- schematic available.

Signal circuit is activated by pressing down on the line selector switch, provided you connect the necessary wires to 5 and 6 via an additional cord and have the proper external equipment.  To switch to line 2, you press down and turn the dial 90 degrees to the right.  The 4-prong to RJ14 connector isn't included with the phone.

This phone ships from Canada via Canada Post Expedited USA.  On the US side, it will be delivered as USPS Priority.  Please provide your phone# when checking out.
