In 1949, 'Eire' became the Republic of Ireland or Ireland, formally free of allegiance to the British crown. Presumably, the crowns lands transferred to the state as this is when the British administration acknowledged complete Irish independence and when Ireland withdrew from the commonwealth (end of 1948). So even though the free state existed from 1922 and the constitution came about in 1937, any such arrangements that may have existed should have ended from 1948 or 1949. I'm no history expert and I don't want to start a debate on this issue, but that would be my understanding of it. Open to correction from any history buffs........
