Not sure, Fred. I’m no expert. Do what I did and look at pic 19. It seems much much easier to make sense of the photos if you go backwards. In 19, it seems clear to me that those are her two feet in the sides of the foreground, with the camera pointing between her emerging feet.
You could be right...so there's neither a rescuer there with a harness, or a diver wearing goggles, just Fuddy with her legs bobbing up and down...with the waves...and she's still got shoes or socks on her feet.
It's that yellow object that is the problem, she was wearing the same clothes as in this image, I can't image her wearing yellow socks or shows with that...
I'm still looking. I might be able to agree on that black blob being her trousers, but that other object that appears to be yellow, that's now too far away to be part of her body. However, it still looks like Yamamoto is holding her hand...but what seems odd, is IF that black blob isn't her trousers, then her face has fallen forward into the water, and her lifevest isn't on properly. It's also possible that the dark blob we think might be her trousers isn't the same shiny black 'thing' that appears out of no-where. There's still part of that film missing imo.
That entire scene needs to be filmed again...
