John T's description and photo says it all. The establishment now Great Expectations Hotel & Bar - I wonder what the original Methodists make of that! The 0.3m above ground level refers to height above 4th step rather than street level.
This may be a 1-GL mark - p235 of the 1-GL abstract describes one 648links (130m) from the canal bridge logged as http://www.bench-marks.org.uk/bm23808 .

Very unusual cut mark with uneven cuts. The centre vertical is very long and the diagonals do not match. Used as a 2GL side level. http://maps.jochta.com/benchmarks.php?id=12
