If you look carefully at the base of the tower, you can just see the remains of the R and the E at the end of EIRE.
There is actually an historic aerial photograph of this sign too which the Military Archives have published on their social media/Flickr stream

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.
Google – the resolution on this section of Belmullet is not clear enough to display the sign.
