Located just outside church yard, buried to top edge appeared to be in good condition.

Found amongst the farm/building debris lying all over the place and with weeds and long grass growing through it all - a right little mess! Close to the stone boundary wall, it's buried up to the top surface; height tag missing. Photos at:

A retrospective entry of my FBM visits already recorded on Trigpointing UK.
The location is adjacent to a farmyard where the detritus from the farm is stored. I suspected that it was under some discarded piping but need lifting equipment to prove it.

Track runs along the edge of a farmyard, FBM may be hidden at ground level by farm fallout, but no railed enclosure that I was hoping for.
