Drove nearly 4hrs. just to bring this single insulator home on Monday (Labor Day) even though it was found about 20-30 minutes away from home. It's a long story. All I can say is this one saved me from being very disappointed at myself for making a distant flea market scheduled trip. Thought this insulator was a B when I picked it up off the table. Turned it a couple times without seeing or feeling any B. Only looking very close did I discover it was weakly embossed W. Brookfield in the front skirt and New York on the rear skirt.
