Here's a cool picture a friend sent me of rarely seen U-1944 Pierre patent porcelain dry spot insulators still installed on the side of a building in the UK! The number was published in the WorldWide Porcelain Insulators Book, 1982 edition. For more details, I highly recommend you buy this (and its 1986 Supplement book!
