In a compound on the West side of a farm track, 100 yards North of Biggin Lane (unmade road).
WELDED All surface features remain intact. The hatch was welded shut when visited in 1997 but on 1.6.2000 it was found to be open and the hatch is now detatched. Internally the post was dry in 2000 but is now (4.1.2002) flooded to a depth of two feet probably due to rainwater. Information received from: Geoff Meads, Trevor Webb & Dan
Opened in 1960 and closed in 1991.
