Visited today and found it in good condition, I've walked past it before and never noticed it. http://www.geograph.org.uk/photo/2326270

Strangely the PB is not on the OS Database or shown on Old-maps, although Old-maps from 1875 to 1933 show a BM of 178.0ft (54.3m) on the NE parapet of the bridge. I couldn't find a mark - this parapet appears relatively new. A photo of the SW parapet is at http://www.geograph.org.uk/photo/2191567. A close up photo of the bracket is at http://www.geograph.org.uk/photo/2191542 and a wider view at http://www.geograph.org.uk/photo/2668529

Vgc. Good parking at south east end of old bridge. Go across the bridge, and go down to the left. The PB is near the (old course of the) river behind some barbed wire.

The PB is approached from the NW end of the medieval bridge. It is next to the Back Water on the SW face, quite awkward to get to and a slightly odd position for a BM, maybe this is why it was replaced by the nearby FB which this one should not be confused with. The PB is not listed in the OS database. http://maps.jochta.com/benchmarks.php?id=40
