Raven;
Don,t have your mother worry, I have found Irish and Uk pension staff very helpful.
Write as per Carrs for Roi update.
If she writes to Centre for Non -Residents ,Room BP1301,Benton Park View,Newcastle Upon TYne,NE 98 1ZZ, I expect they will help or point her in correct direction..
Just ask for confirmation of years she worked there.
In any event when she gets the Roi breakdown , she can make a good stab at it , I think after 31 years+ no-one is going to get too strict!
