AAF 15 (11:8)
AvSM 11-FB 1
ASM 400/3 (day after Ben's murder)

Not sure when the other flashbacks take place. fb2 is early after the death, fb3 would be a few days after. fb 4 is presumably after fb3, but with Peter looking unshaved could be quite later in the chronology, not wanting to get up on the day of his uncle Ben's death anniversary and at a time in his chronology when he still lives with his aunt.
(I wonder what is the earliest story where we have seen Peter shaving or unshaved, I think not before 1979)
