--** If you look in 250-140 of any newer code book is shows what "was"

Could be; I don't have a copy...

Doesn't really matter; the old rules are no longer in effect but did seem
worthy to correct the idea that somehow all those earlier installations
were not Code-compliant at the time and only were allowed by (essentially)
dishonest inspections passing violations.

** What we have here, is a total misconception of the code on the part of
some of these posters. The rules for non insulated neutral/ground use on
cooking and electric dryers are still applicable. New installations must be
4 wire, but existing installations are perfectly acceptable, if they were
done properly to begin with. The rules simply required that the non
insulated ground/neutral is part of a type "SE" cable not smaller than 10
gauge, originating from the main service panel. I never suggested that a
two wire cable with uninsulated ground wasn't acceptable, only that 10/2g
Romex was never acceptable, as it is not type SE, the only acceptable type
of cable that can be used for this purpose
