10 June 1956
stated · refuted
Why
pm-actor-525: 10 Jun 1956 is transcript 1019's night, event 1246; event 40 is the 24 Feb 1956 delivery of the same title (catalogue #36), with no known transcript.
Reasoning
Node 1019's own delivery date shares the catalogue's year but not its month/day, the more plausible shape of a catalogue slip; preferred over the bare day-guess.
