I have a California residence built in 1962.
The EGC is a bare 14 awg wire run separately to metal outlet boxes in the kitchen, bathrooms, garage and outdoor boxes. It generally follows the 12 awg fabric wrapped NM, but not always, usually under the same staples and branches off with barrel crimped additions as needed, even to different circuits. The EGC is bonded to the boxes with grounding clips. Non-bonded boxes, such as switch boxes, are made of Bakelite.
It is an interesting solution. I am wondering which NEC code cycle this stopped being practiced, and when did grounding conductors need to be included in the cable. My searches has been fruitless.
