I really wasn't looking for insulators when I found these. There is another string of three on the other side of the pole. They are Ohio Brass pieces. I also found some earlier carmelish colored suspensions under an old power tower for lack a better word. The grass and thorns were up to my neck under the tower, but there was a nice pile of suspensions partly burried to pick through. I didn't bring anything home mainly because these are on an island and I didn't have help to cary a pile of suspensions accross the only way on and off the place, an active railroad bridge over a river see [id=279279252]
