Robin I accept your original argument but proving it through Altgens 6 alone is it's own puzzle, which is fascinating to explore. If the Z film was accepted it would also prove Chaney was not where they say he is cause he obviously is not there in z255.
Thanks Chris
Their rationale for Chaney not appearing in Z-255 is that someone somewhere altered the frames to REMOVE Chaney.
I would ask them these question:
Why on earth would anybody want to Remove Chaney from the Z-film ?
If Z-255 how many other frames was Chaney excised from ?
Why wasn't Chaney excised from Altgens 6 ?
Why wasn't Chaney's motorcycles reflection taken off the back of the limo in Z-255
Some clean up operation, who was running the "Operation Remove Channey" the 3-stooges
Inquiring minds want to know .
