I picked these up from the S Manhiem-Donegal 69kv line. A lot more of the old line was just taken down, and the crew let me take these right from the scrap truck. The maroon ones are unmarked Pincos from 1928 and the grey ones are Chances from 1972. There are also a 1950s Pinco and Locke disk in there too. If anyone wants any of these, shoot me an Email and hopefully we can make a deal.
