A rather strange OS cutmark on a wall at Tern Farm; the arrow mark seems to have become 'disconnected' from the datum line and now sits at one end of it, rather than pointing at the middle. Not seen one quite like that before. There's no obvious sign of the wall having been rebuilt since the mark was last verified by the OS in 1966 at 65.640m above Ordnance Datum Newlyn, so it may always have been like this.
