After a recent post on this subject I have been looking out for the white 
insulators. On the Pumpkin Vine near Starkey, VA they are located on the 
lowest arm, nearest the track. At one time they may have existed on all 
poles, but now most --but not every-- pole has two white insulators. When 
they are not white they are usually clear.

The other insulators on the pole are a mixture of clear and green.

I have not spotted any white insulators on the Main Line through Vinton, 
VA. Just a mixture of clear and green. Did this line ever have white 
insulators? Or were they only specific to certain divisions?
