[TowerTalk] early 70's tower

[Benson]

  I got some information by phone about a standing tower that is for 
sale. According to the current owner, it's 65 feet, triangular cross 
section, about 28" at the bottom and getting narrower toward the top. 
I'm assuming it's galvanized steel. It is un-guyed and apparently some 
of the bottom portion of the tower was buried in concrete so I guess it 
could have originally been a 70 footer.

What things should be a red flag when I look at it? Any clues about who 
might have made it?  I think it has television antennas on it now, with 
at least one on a rotator.
