I found these on the CSX where they had removed the poles last year. It looks like I missed these when the weeds were high and someone found these and left them by the pole stub along with a broken Hemingray 42. One of these was embossed H\EMINGRAY-45. It looks like there is an "N" between the "H" and the "E". It was Friday but I was finding things in twos so it must have been "Twos Day".
