Sharing the neutral from another wire

Found this the other day the bank said it needed to be repaired. Old knob and tube using the neutral from another line.

Is it actually using the neutral from another circuit or is a failed K&t neutral being replaced by the white conductor?

Is that all they want repaired?

No there was a few other electrical problems they are going to have looked at

Didn’t I just see you on a flight from Asia??

we can probably forget venturing into Box Fill questions at this point…lol

No need to if the cover has been discarded :smiley:
