Yes, and even into the mid-80s, three-conductor cables typically included
three "ropes" of twisted paper or polyester fiber spiraled with the
conductors. It gave the cables a fairly smooth surface, instead of the
rope-like surface that's typical now. 14-3 cable used to be about the same
outside diameter that 12-3 is now, and 12-3 was pretty darn fat.

Probably not.

I don't see any reason why not. What you describe is pretty well normal for
the older 12-3 cables.
