There are three near here, quite unusual, they're usually more spread out.
The first is near a pub, is has D posts around it, supporting F rails. B is the last number of a nearby box. (edit: the box has gone, B=3)
The second has a lid, if you were to open it the base of the lid would face towards A. (North = 4, East = 2, South = 1, West = 3)
The third, about C 50 metres from the first, has a small hole in the top, shaped like a regular polygon with E sides.
