Cleaned the black stuff that you see in this pic. Must have been melted wire covering or like. Came off very easy with soap and water. Embossed HEMINGRAY / MADE IN U.S.A on front skirt and D-512 on rear or EIN 030 if you prefer. Don't see any damage at all. Very nice!!

Book says 50-75. Have this one shipped to your door for $75 in 2-3 business days once payment is made. Add $7.50 if you have a Canadian address. I accept Pay pal in a non-fee mode, personal and money order checks as payment. First email. I do combine shipping but be sure to contact me about this insulator before searching for others I presently have listed here at Icon.
