We live about 700 yards from railroad tracks and when we moved out here we explored the 160 acres of very primitive land next to us, with the owners permission. Along the tracks we found many many of these insulators and brought many back and stored. There were Hemingray, Brookfield, Star and many other brands with two Whitehall Tatum deep purple ones. We soon found out they wouldn't make us rich. Now in the spring when it becomes warm I pick out 50, put them on a plank in my outbuilding and run an ad under "Free" offering the lot of 50 to the first one out. No picking and choosing, you have to take the whole lot. We've done this three times and only two or three people have called us each time to see where to come out. Better than sending them to the landfill.
