This sign was linked to LOP58, given as Corraun, Co Mayo. It’s actually in the Currane estate, a little further east than Corraun I think and it’s not in the worst condition, The number is still in place, although slightly damaged.

Note the coastal erosion which has clipped the corner of the box. Also note that the number was very clearly added later.
