Here are two Lorenzetti's from Brazil that are next to Moosehead Lake, up in Maine on the Former Canadian Pacific. There are 2 on this pole, and one on a pole down a little ways. They looked to be Coated on the top. The U-Number is 2231, and is near worthless, because they are newer. (Thanks to Elton Gish for the info!) I plan on getting the one farther down this summer, because I enjoy looking at these ones. These are the only ones like this I've seen. The only other signal power insulators are Gray Canadian Porcelains (Most commonly found among this line), and Ohio Brass's. There are also a few cable tops I just haven't found yet, west of Onawa Trestle, around Elliotsville twp. Thanks!
