Courtesy of SBC Archives and History Center, San Antonio, Texas All phones in the display are touch tone with 12 buttons, with the 0 key in the lower left, rather than center position. The 3 Trimline designs probably dates the display to about 1963-4. All are probably design models and not functioning prototypes. Any information on this display or where it was used is appreciated.
