On the North side of Knights End Road, West of the A141
LOCKED All surface features remain intact and in very good condition. The post was dug up in the 1980’s and completely rebuilt. Both the ventilation shafts are larger than standard and of a different (squarer) design. The FSM tube has never been painted and looks as new. The post was re-sold in 1999 and the new owner hopes to restore it to operational condition.
Opened in 1961 and closed in 1991.
