The telcos may have stopped installing open-wire transmission lines
in the 20s, but the existing ones remained in use well into the 50s.
Some here may recall that that was when the deluge of green glass
telco insulators in their myriad shapes and sizes hit the
collectible markets. As the wires came off the poles to be replaced
by multi-twisted pair cables the insulators were often left in
place. They were then scavanged by enterprising people for their
own collections or for re-sale. This continued through the 60s in
various parts of the country.

Some years ago they totally got rid of the line along the Trans line
from Kalgoolie to Port Augusta. Not only did they salvage all the
wire, not much, a lot of it was SWER, but also the poles as well. This
was a disaster for the eagle population, as they used the poles for
nesting. So they had to build towers every mile or so for nesting.

That was a VERY expensive salvage job!
