In a small rectangular compound straddling a field boundary on the west side of an un-named minor road.
OPEN All surface features remain intact with the grey/green paint in good condition. A metal dome on the ventilation shaft indicates this was a master post although the dome has been removed and the hole filled with hey (perhaps a nest). The hatch is locked but internally the post is in good condition. When visited in 2000 the post was locked it is now open. Remaining artefacts include the table and shelf (detached), cupboard and copper earth straps around the walls. Opened in 1964 and closed in 1991.
