  • Original Primary "Yr Eifl" (same FB) has gone, replaced by The Rivals (rebuilt using same FB)
  • jonglew says...
  • Yr Eifl is the original pillar, computed 1937. OS records it destroyed October 1961. Replaced by The Rivals which was computed 1961 and is extant as at Aug 2015. Both pillars have the same FB number.
