Niagara, Lockport, and Ontario Power Co. dead end array at Rochester, New York. This is how you dead-end a conductor without the availability of reliable suspension insulators. Imagine the strain placed on these insulators when the conductor got coated with ice or started to gallop.

I know just somewhere out there is a mint M-3890. I just refuse to believe that out of the tens of thousands of insulators made; there isn't a mint one laying out there somewhere to be found. I'm curious as to what sections of the line have been hunted in comparison to what is still out there. Most likely the right of way of the West Shore railroad is all that has been searched since finding the locations of the other sections of line is very difficult. These insulators are very important in regards to the history of modern day power systems.
