These are all taking an acid bath now. Amoung this days find is a CD 126.1 Brookfield Fulton St. NY. with patent dates. The first one I ever found unbroken. The same with the CD 156.1 (third from the left). This one really made my day. And imagine, I was ready to call it a early day before I decided to check one more section of track before calling it quits!
