Here is a not-so-common Holmes tree bracket (top unit) embossed PATENTED in pristine condition with what appears to be brass coating on the threads. (The color of this is most accurate in the upper right photo.) The insulator is a CD 160 EIN [030] (F‑Skirt) HEMINGRAY‑14 (R‑Skirt) MADE IN U.S.A. RDP in Hemingray Blue. There is a pinky-nail flake at the base of the rear skirt that takes out one drip point and slight wear on the rear embossing where it contacts the bracket. These often go quickly when offered for sale. Add this one to your shelf for $150 plus postage.
