My latest house had an early 60's build date. Ground rod outside, as well as wire to where the water pipe came in the house.
100 amp Federal panel, main, range, dryer, water heater and sewer pump, and then 15 edison circuits.
Outlets all grounded, just that the cloth covered wire had a really thin wire for the ground.
Replaced it when the dryer fuse got hot enough to burn the end off of the cartridge fuse without melting the link.
I think what our beloved Reno was saying is that a range/4 might be suspect in the grounding dept.
