Last Saturday I took advantage of the 60 degree weather (that is unusually warm for PA this time of year) and went back out to the trestle at Safe Harbor. I looked in a spot I missed the other times I went and found these. The two smaller suspensions are Ohio Brass and the big one is a Locke high tension bell from a catenary wire dead end. There were 3 in the string, with this being the only one that wasn't smashed.
