Interesting, LF 222's reg is 241 C 7906.Not a bus nerd, but I saw this bus making what I presume was the end of its journey to Cork the other day, on the South Ring. It was traveling in tandem with another bus which seemed to be the same and which had a sequential registration number (7905 or 7907, can't remember which).
Perhaps you saw LF 221 and 223 ?
Must check that out, what day was that ?
