Found these four light puple B's in a vendors crate at the flea market I go to religously just about every Sunday. It's my belief these originated off the West Shore Line located upstate NY. I was pleased after cleaning them to find at least one had some olive stringers or squiggles. The seller said I puchased insulators from him in the past but I didn't recall. I will B for sure looking in the next crate he promised to bring next week. To see the other insulators I picked out of the same crate [id=313150435].
