So far this is the only B&LE RR date nail of this type I have been able to locate. Again, this was one not known. Later Matt Kancle found a larger diameter one - see next pic. I traded this one to a B&LE specialist, although I hated to see it go, b/c I figure it fit better in his collection. What did I trade it for? A great PRR lantern, PRR milk can, and a CD 116 Hemingray. I told him this was too much for the nail, but he wanted it bad and wanted to make sure I was very happy.
