Drove to within 4 metres of it with Iain Brown, so found easily at this time of year.

In good condition. Clearly visible from the roadside at this time of year but could well be subsumed into the undergrowth in summer.

looked for a while but found on the small flat piece of roadside on the right going up from the A390 just before the entrance to a farm (house?)
as before the FBM was well hidden in the undergrowth but moved enough for a photo otherwise in good condition all intact even has the height plate @ 290.03 ft.

This one survives. The verge is easier in February. The FBM is set against the bank, and was hidden by grass. The only guide I can give is it is opposite a gap in the white line. I left it clear.
