Hello again.
Have always looked at various pictures and movies, but with very disappointing result.
As for the person in the Bronson photo, someone came to me on the Patsy Paschall film, which could be the same person. Whether this is the Babushka Lady is more than uncertain, so it is hardly worth keeping track.
Here is the Photo:

In addition, it seems as if the Skaggs photo someone in the inside of the vehicle is reflected in front of the Allen-Skaggs-Babushka Lady stands (on the windscreen, except perhaps the sky does not reflect anything, so the reflected object must be in or behind the vehicle are located).
But maybe I can see ghosts now, here are the pictures:


The Skaggs photo gave me the idea that the Babushka Lady might have reflected on one of the passing vehicles like the presidential limousine in the Muchmore movie or another vehicle in the Bell movie and Allen-Foto (for the Allen-Skaggs-Babushka at least). Unfortunately I could not recognize anything yet.
The problem with the reflection is that the Babushka lady, if it is too far away from the vehicle, would most likely only reflect on the body of the vehicles, as the car windows are more likely to reflect upwards. This reflection on the body would shrink the babushka lady very much, so that you need a very good image editing program to maybe make something visible (in addition, you get in danger of pareidolia to expire

). Nevertheless, I will continue to try to find something.
Wish you all a nice and happy New Year and much success and new insights in your research.
