Note: I received the following e-Mail from ICON member Matt Kancle with some good information that I found very educating.

I have been enjoying the variety of insulators you have found in Pennsylvania! The unembossed CD 133.4's were used on an overland telephone (former telegraph?) lead that ran along Route 21 in the Waynesburg area. I found a large chunk of one near the Scott covered bridge 15 years ago. I remember talking to the Plunketts about this line and they said they knew of a lineman many years ago who worked on it and found quite a few wormsers, including an amber one.

Not saying the 133.4's weren't used on the railroad lines around Washington and Waynesburg as I believe it was a very common telegraph insulator 120 years ago. (I found a purple one on the B&O near Confluence, Pa, an aqua one the D&H in New York, and a purple shard along an overland toll line near Kingwood, WV.)

Take care,

Matt
