I need to connect a new traveling cable that has ground with some old (possibly >50 yrs old) armored cable that has only black and white wires, i.e. no ground. I wonder if it will be OK that I just piggytail the new cable's ground and wrap it at the grounding screw in the connecting receptacle.

thanks

merci but i have to use armored cable because the circuit spans 3 floors (code reg in my jurisdiction). attached is the photo i am using. and i always go with metal boxes/receptacles.
