Here is a CD 257 glass insulator. Nicknamed 'Mickey Mouse' due to the resemblance to the Disney character. Embossed HEMINGRAY - 60 over 0_4 followed by two rows of 5 raised dots on one skirt. Also a dot to the top left of the '4'. MADE IN U.S.A. over a 6 is embossed on the other skirt. Round drip points. A light straw / off clear color. The number embossing 0_4 means the mold was made in 1940 and the 11 extra dots signifies this insulator was manufactured in 1951. A 3/8 inch bruise to the extended ridge in front. Pinhead tick to the underside of that extended ridge in the rear. Small ping/bruise to top back of the right ear. My insulators have been cleaned only with a sponge and water - some could use a better cleaning to make them shine. All my auctions start at $1. Successful bidder will pay USPS Priority Mail shipping for a 2-3 pound package. I will always combine more than one auction win on the same day to reduce the postage costs. Ask about other accepted payment methods. All insulators from a smoke-free environment. As a rule, I do not sell fake or altered insulators. Thanks for looking and good luck!
