Antique Faire Finds:

On the left is an aqua F-Mold CD 123 EC&MCo.S.F. Condition is rough, but you hardly ever see them for sale outside of an insulator show.

On the right is a GONDA trademark battery jar for telephone work. Never seen paper label which is a combination of advertising, instructions on battery use, and marketed by California Electrical Works.

Also in the box of insulators that had the EC&M, there was a sage green Hemingray No. 19 that I overlooked as I assumed it was a McLaughlin insulator without checking the embossing.
