Here's one that's been nagging away at me for a while. At the north east side of Heathfield in Sussex there are a batch of posts made from what looks like bullhead rail. I've never seen these anywhere else. Not until last week when I took a rarely used route to the south on a parallel road toward Battle. Once again a short section of road with similar posts. The second road must be a few miles directly south but unconnected to the first.
The questions are why are they made this way and why here on two roads near to each other, but not connected? Is it rail? And if not, why do it this way and not use the normal posts?
