Embossed HEMINGRAY / 13-41 on front skirt and C.S.A. on rear skirt. Can't find any EIN's without dots after numbers so can't say whether this yellow insulator is unlisted. Has a milk whisp with white junk in the dome and a little more milk elsewhere. Also has the metal insert to prevent glass breakage when instaling. Mint condition. $35 shipped to your door. First email regardless whether you use Pay Pal in a non-fee mode or send me paper. I will also combine shipping with any other insulators I presently have here at Icon. Don't expect to much of a discount unless you buy more then two. Sold eBay $26.10 shipped
