I found this at a recent flea market. It is a CD 162 EIN [110] (F‑Skirt) HEMINGRAY‑19 (R‑Skirt) MADE IN U.S.A. SDP in Hemingray Blue clad almost entirely in painted stainless steel with only the dome exposed from the outside. The base is seen from the bottom where there is a chipped inner skirt and a couple of halved sharp drip points. It was obviously attached to something based on the wear marks around the holes, and there are some remnants of cork, which I'm guessing was a gasket of some kind, still stuck to the base. I can find no seam(s) in the steel, although you can see where the armor bends around the mold lines of the insulator. The steel itself is fairly heavy gauge as I can't bend it with just my hands, and I don't see how it could have been used as an electric insulator since the metal covers the wire groove and would make a connection with whatever the base was attached to. Plus, there are no wear marks in the groove. My first thought is that it was used as a cover/diffuser for a light of some sort. Anyone have any info as to what this was really used for? And how they wrapped the seamless steel so tightly around the insulator without breaking the glass? Thanks for any help.
