I was here for a geocaching event, but whilst here I thought I would visit the FBM.

In deep cover, railings and all, opposite Nelson memorial column. Cleared away some of the vegetation. Large bolt only on top surface, differing from the usual type as no provision for a height tag. Photos at:

Opposite Nelson momunent, with good views out to sea. Pillar itself is in good condition, though the railings surrounding it are badly bent and the enclosure is heavily overgrown, needing vegetation removal to inspect the pillar closely. Pillar is early style without height indicator on top Bolt. It has a GPS PSD plaque, but no cast plate (which would normally be expected on an FBM) - subsequent research in OS records indicates that plaque had been buckled, and was removed during maintenance in 1969 - the implication in the note regarding this (a reference to "altitude plate") is that it was the earliest style of plate which included space for the height information.

Located next to Nelson Monument, very easy to find, the "playpen" is looking a bit tired, and seems to used as a dumping ground, at the time of this visit, there was an old television and radio lying next to the FBM.
