A very hard to find 3-pack of Circle F fatboy sockets with pin-and-keyslot shells. These are stamped 50 C.P. or candlepower, the rating used instead of the term "watts" pre 1910. The sockets were thoroughly cleaned inside and out and were tested with an ohm meter and with bulbs as you see in the photo. They work—the switches still have crisp action. The shells have an antiqued look as shown and received a coating of museum grade wax. The paddles are intact with no splitting. The insulators are new; the caps are original but still in good condition. The screws on the base were resealed with liquid rubber. One of the small pins on one base is missing, but the shell still snaps solidly together with the three remaining pins.
