I just looked this Bad Boy up at> http://www.nia.org. Light green Petticoat CD#164. Has embossed H. G. Co. Patent May 2 1893. With sharp drip points/smooth inter skirt. I remember buyin these at a Antique shop way up in the UP Michigan. I bought a sack full for 1.00ea back in the late 70s. Good pick, cause this one is worth 200-250! Most of my stuff is packed, cause we have our house for sale. But I know for sure that I also have a Westinghouse No 6 too. (light green) It's worth 500-600!! I need to go too a insulator show soon! Happy Pickin!
