When asked two simple questions you both duck and weave, and try to divert from answering my direct and specific questions ,so i will ask it again.
Your rationale for Chaney not appearing in Z-255 is that some one some where altered the frames to REMOVE Chaney.
(1)-Why on earth would anybody want to Remove Chaney from the Z-film ?(2)-If Chaney was removed from frame Z-255 how many other frames was Chaney excised from ?
If you can't answer these two simple questions, then your whole "Chaney was removed from the Z-frames scenario" is just a dumb theory that hasn't been thought through very well.
A mystery "who dun it" in search of a motive.
