**The use of insulation

permanently reidentified to indicate its use as an ungrounded

The other parts of that article apply to the travelers and so on in 3 way and 4 way switches and so on…but the basic still applies…it MUST be indentified at BOTH ends…
However as Gerry has so well stated…what we CAN’T see is the problem…where are these K&T wires terminated, are they in a junction above the panel…are they done correctly…are they supported correctly and so on.
Yes, Agree 100 % to defer…defer…defer…
