I'm kinda' glad I brought this one home. It was the only intact insulator I found while searching this stretch of track in western Warren County, PA. The PRR and NYC once had parallel lines here. The PRR is still used by the Buffalo & Pittsburgh and the NYC has been abandoned since the late 1960s. This lowly WT CD 155 has a nice color! The Coke bottle is embossed 'WILLIAMSPORT PA" on the bottom and dates from the mid 50's.
