CD 121 refers to a style of insulator that would be made by several companies. This one was made by McLaughlin Glass within 1920 -1935. It was another California based companies.
The unusual point about this piece is the dark green color. The normal colors for insulators was clear or aqua but this one is a dark green color. The reason for unusual colors is that insulator companies would use left over glass. In this case McLaughlin bought a truck load of old gin bottles and made them into insulators.
