From study of aerial photographs and contemporary records it is clear that the anti-tank defence line crossed Old Heath Road south of Old Heath Cottage (now demolished) and followed a water-filled ditch from TM 0162 2304 to TM 0180 2321. Here, the line "bridged" via two anti-tank cubes to a small watercourse on the edge of the sewage works. Contemporary records state, "2 concrete blocks. Old Heath Market Gardens, Old Heath, in S.E. corner. Map ref. ??5415". (Mil. Ed.) <1> The two cubes can be seen on an aerial photograph taken in October 1947.<2>

Nothing was found at the time of the site visit, and nothing can be seen on post-1960 aerial photos, but it is nevertheless possible that the cubes still survive in the dense undergrowth.
