An OS cutmark low on the wall of Image; most recently levelled in 1972 at 286.619m above Ordnance Datum Newlyn. Its style makes me suspect it's older than that. Edit: Indeed, it's shown on the 1883 map at a height of 940ft 6in, which means it dates to the 1st Primary Levelling of England & Wales in the 1840s or 1850s, and will be a height above Liverpool Datum.
