+1 what Gary said.
The shielded cable was put there in an effort to reduce the possibility of AC hum being introduced into the radio (chiefly, the audio) circuitry. And it was grounded only on one end because that was all that was needed - if it is grounded on one end, it is grounded through its entire length.
As to cloth covered wire with different color tracers (or, in your words, "ticked") - the answer is no, not in the size typically used in vintage radios (20 gauge).
