Pyrex insulators used for electric utility applications are a pretty rare sight in southern California.

Note: All of the photos I recently have been adding to this album are from my former vintage insulators group on Yahoo. They closed their groups last year and I am sharing many of the pictures I saved from the group's albums. Practically all of these photos were taken by Rick Shields, who loves insulators and lives in southern California. Thank you, Rick, for your great work and for allowing me to share your images with the rest of the ICON community.
