This is an old PG&E pole with the scarce still in service mushroom shaped multiparts. This particular street, in Grover Beach Ca., on the south central coast has quite a few of these poles still in use on what is obviously, the oldest power line in the town. The multiparts are Locke M-2360. The voltage is 12,000 in a delta configuration. Again, glass signals were the predominant secondary insulators on Pacific Gas & Electric Co.
