I got these from the crew working on the 138kv re insulating job. Apparently one of the lineman was collecting the old bells too! I was able to score more Thomas bells from 1948, and some OB bells from 1951 with a flatter profile. The 10" gray bells are Lockes from 1979 and Pincos from 1975, and the 9" bells are GEs from 1973. There is also a pair of Chance 9" bells in there from 1965, which make them the oldest gray suspensions I have.
