Spotted this awesome blue porcelain combination today. It's located at 6th and Jefferson street in Klamath Falls, Oregon. The Robbins Egg Blue large pineapple style spool is really tough to get in this color. This color spool seems to be very fragile. I have never recovered one that did not have some damage as this one does too. The two cobalt blue Ohio Brass are looking good as is the small 6" Victor dead end strain insulator. Colored porcelain was used by COPCO as neutral phase indicators. Various shades of blues and grays along with an occasional camo green are still seen in service even today but are disappearing rapidly!
