I bought this insulator in a northern Indiana antique mall on the way to one of the early Jim Crandall Wheaton Ins Shows. A decidedly bottle orientated dealer displayed a a hand written poster stating "Everything in the booth is half price except for the bottles". I bought this $3 insulator for $1.50 .... I wished, I'd saved the receipt. N. Indiana was ground zero for Westinghouse insulators .. back in the days.
