That last monopole for the guy wire is to bring it down at the line crossing point and thus get extra clearance from the 500kV circuit over it. It had to be pulled out of span to do this, as the alternative clearance wise would be a flat arrangement of the phase conductors on H frame or similar towers, and doing that must have been too much of a pig.
I believe they are from the 1940’s at the latest. The circuit runs through private land to an old style 34,500/19920 to 4160/2400 substation. Transformer is dark grey-black. Probably loaded with pcbs.
@@metersocket00 the oldest substation I’ve seen was using a westing house transformer from the 1920s. I’ve never seen distribution lines as old as that.

I have never seen transmission lines that old. Or distribution lines. You should try to find an older substation.
