There was no ACC signal being broadcast in 1954-56. None of the early color sets had and automatic color correcting. They all used a color oscillator phase locked to the burst. Some designs had a crystal in the loop, others (like Westinghouse and Sparton) did not. The Westy used R-Y/B-Y demodulation as opposed to I/Q demodulation.
