This EIN 010 No Name CD 142 has the copper liner. That copper lining has patina on the inside and you can see that patina through the outer skirt as well. According to price guide this insulator is a Hemingray product. The condition is mint as far as I can tell.

Book says 40-50. Have this uncommon Hemingray insulator on your door step or on your shelf in 2-3 days once a one time payment of $55 is made. Add $5 if your address is north of the U.S. border. I accept Pal Pal in a non-fee mode or personal and money order checks as payment. I will combine shipping and give shipping discount other insulators I presently have listed for sale here at Icon. However, you better email me about this insulator first. Being I have a first email policy you wouldn't want this one to get away while you are shopping for more glass for your insulator fix!!
