Date (happened)
between 1931 and 1937
unresolved
before 1934
bound

Neville explicitly situates himself with Abdullah in New York in 1933 while identifying their five-year Hebrew study, so the study occurred before 1934.

Reasoning
Neville met Abdullah 1929-1931 (chronology 962/771: 1931 dating, Kabbalah letters 1930..1931) and was already his 'old friend' studying with him in 1933 (passage 527378); five years of study therefore straddles 1933 and ends about 1936-37. Endpoints are not stated.

Reasoning
The telling occurs in passage 527378 of nid 989, whose strongest live delivery claim is 1948-02-23 certain/preferred; the told row inherits that date and no higher confidence.
