Neville recounts his 1934 voyage home to New York after three months in Barbados, a trip he had made at his brother Victor's unexpected written request. On the ship north he fell back into old habits, drinking and smoking again after months of abstinence, and he ties the lapse to a warning Abdullah had given him before he left: that only after proving the law would he 'come out of that graveyard' of forced holiness.
Date (happened)

stated · probable · preferred
Reasoning
Neville names the year himself in recounting the return voyage; probable rather than certain because it is a decades-old personal recollection, not an external record. A second telling in nid 1033 (passage 528246) narrates the same voyage in more physical detail ('ten or twelve days at sea') without repeating a year, but matches this account in every other particular (letter from his brother, three months over Christmas in Barbados, the ship north) and so corroborates the same 1934 event rather than adding a separate date.
Told / reported
February 1948
estimated · probable
Reasoning
Lecture nid 989 carries two mutually-preferred, mutually-exclusive certain catalog claims (1948-02-23 and 1964-02-03). An independent chrome-header/transcript witness (d2) corroborates 1948 at year precision, so preferring that side of the conflict per the transcript-over-catalog guidance. Capping at month precision (1948-02) and 'probable' confidence rather than borrowing the catalog claim's exact day, since the day is not independently corroborated and the two conflicting catalog rows do not even agree with each other on the day (23 vs 03).
between 1957 and 30 January 1969
estimated · possible
Why
Flagging lecture nid 1033 for the dating-conflict lane: three certain+preferred=1 legacy catalog claims twelve years apart, none independently corroborated.
Reasoning
Lecture nid 1033 carries THREE mutually-preferred, mutually-exclusive certain catalog claims spanning 1957 to 1969, and its own processing notes record that no dating investigation was done on this lecture. Per the v1.1 rule for conflicting delivery claims, writing a between range spanning the full disagreement at possible confidence rather than silently picking one.
