After the show, I chased an old power line North out of Chehalis that still has a lot of porcelain multiparts in use. April, 12, 2003. I suppose that I should have put this in 'Insulators in Service". The old poles with the 3 section pintype multiparts are getting hard to find anywhere, these days! The multiparts on this line appear to be PINCO from the 1920's.
