If I took a pic of this insulator in the snow we've been having all winter long in the North East USA you wouldn't be able to see the insulator. That's how pure white the milk glass looks to me. This one is an EIN 010 with tiny sharp drip points under the base. Embossed MAYDWELL-20 on the front skirt and U.S.A. on the rear. The condition is mint.

Book says 10-15. Have this insulator shipped to your door within 2-3 business days once payment of $22.50 is made or take pair for $35. Add $7.50 if you want shipped to Canada. I accept Pay Pal in a non-fee mode, personal or money order checks as payment. I will combine shipping so see what other insulators I presently have for sale here at Icon in the for sale and for sale (not sold) albums. Be sure to email me about this piece before going off looking for other glass. That is if you don't want it to get away
