Here is another item. This one I do need some suggestions as to what it is.
It's a small metal plate, about 6¼" x 2¼", painted black with the number 2622. On the rear are four folded over metal clips. I found it by the trackside on the DSE section around a mile south of Killiney in about 1967 / 68. From the number, 2622, I assume that it came from the AEC railcar of that number, but as to its purpose and to where it was attached I have no idea. One suggestion that has been made is that it was attached somewhere on one of the engines / transmissions. Has anyone any more ideas about this?
