I got this at an auction where the garage was made out of crossarm and poles, along with 13 corn flower, 3 teal green, and 23 blue, 106.1 duquesne's. This was about 5 years ago, and the insulators were in the garage as junk at the end of the auction after 8 hours of griswald cast iron and about 300 guns. There was also about 250 other insulators along with the B. Thanks for looking, John Mesmer.
