I have to admit, that magnified image looks a lot like a fat lady similar to photo of Sarah Stanton.
However the fact that PM is such dark clothing vs how white the fat lady’s clothes are, plus the hair going from dark to that light/white hair, kind of leads me more towards the place Alan Ford located Stanton on the front strips as the white blob of a person with both hands up shielding her eyes from sun.
Also it could be Stanton there by herself, yet she did not move there from PMs corner, rather simply had moved from where Alan Ford has her ( which I still agree with too) at the east side of the center handrail just Next to Lovelady on the west side of the handrail.
Ford will have to post the film frames or Altgens photo no.6 here in this thread to demonstrate
To Mr.Doyle where we think that Stanton was at the time of PM image captured in Darnell and Weizmann films.
