If I had to guess as to why older wire is thicker than new wire with
the same gauge rating it might be more of a quality control issue than
anything else. I bet the manufacturing process today is more accurate.



Today's process probably HAS to be more accurate. Heard a science thing last
week on the radio. In this country, there is now more copper installed in
houses than there is in the ground.



Yeah, and back in the early 70's, there was a wide
spread claim that all of the U.S. copper mines
would be mined out in 20 years.
