The bituminous friction tape used to join wires then is all but impossible to get apart now short of just cutting the wires off. Any remodel work, like adding circuits, two way switches, new lighting means taking out the whole works and replacing. It's not a bad idea to replace existing cotton canvas and asphalt wire after 70years anyway. It works, probably fine, it's just a little unnerving witnessing it there, and trouble to change.I’ve got 5 knob and tube… circa 1920-30
