Proof Rosemary Willis had started looking towards the TSBD by Z-145

Here is Tina Towner's last frame:


...
In her Sixth Floor Oral History from 1996 she said the first shot occurred 4 or 5 maybe 6 seconds after she stopped filming - see the 1:14:40 point of the video:
 


This is consistent with what she previously said she did between the time she stopped filming and the first shot, although her previous estimates of the time were 1 or 2 seconds or a few seconds.

In Trask's Pictures of the Pain (p. 217) Trask refers to Tina Towner's interview from an article in Teen Magazine, from June 19, 1968 in which she is quoted as saying that just after she stopped filming:

"Now I was beginning to leave when I heard the sky fall in - the loudest crack of a rifle I had ever heard! At that time I had the least notion that it was a gun.  The truth of the matter was that I thought it was a fire cracker."

So her memory is that she was beginning to leave after stopping her camera and before the first shot.  The president had passed by and her father had walked farther down Elm St. so she was not intending to do any more filming.  She doesn't elaborate on the time that took to begin to leave but I suggest that it is consistent with her estimate of 4-5 maybe 6 seconds after filming before the first shot.  Even one or two seconds after she stopped filming does not fit a z124 first shot.

I agree with your last sentence. For what it’s worth, here is part of what Tina wrote in the epilogue of her book:

I noticed some minor discrepancies between what I recorded in the oral histories and what I now remember. Going through my files helped make some things more clear. If anyone wonders which is more accurate, I would lean toward my book rather than the oral history.

Frankly, I think that relating the time of the first shot to just after the end of her filming segment is something that she most likely would have been able to do accurately (because our memories are quite often based on those types of associations). However, I think that remembering exactly how much time might have elapsed between the end of her filming segment and the first shot would be much harder to gauge accurately. Therefore she gives a range of 1 or 2 seconds (if that much, aka: or less) in her book. That would place the first shot somewhere close to the Z133 time.

If that was all the evidence as to when the first shot occurred, I might find your point persuasive, although 2 seconds would put it around z150. 

But it isn't.  We have Croft who said that the first shot occurred after he had rewound his camera to take another photo after taking his photo at z161.  Betzner said that he took his z186 just before the first shot was heard.  Mary Woodward said that JFK's last smile and wave began before the first shot.  Witnesses between the lamp post and the Thornton sign said that JFK had just passed by where they were then the first shot sounded. Occupants of the VP car said that their car had just completed the turn when the first shot sounded - it is still turning when last seen in z180.  Occupants of the VP Security car said the first shot occurred as they were completing the turn (along side the TSBD) - it is about there in z191 when last seen.  Jane Berry, the 7th person west of the lamp post near the Thornton sign said that the first shot occurred as the President's car was passing by her.   

So, if one tries to fit Tina Towner's recollection to the rest of the evidence, 4 seconds is a better fit than 2.

  Tina Towner - "Now I was beginning to leave when I heard the sky fall in - the LOUDEST crack of a rifle I HAD EVER HEARD".
                       
                       All of you are assuming Towner heard the Carcano Rifle being fired. Maybe she was hearing the sound of a Different gun/rifle being fired?

Others provide evidence of location of the rifle in the sixth floor SN. Dearie Cabell, upon hearing the first shot, looked straight up from where she was facing as her car (next behind the VP security car) entered the intersection and saw a pipe extending out of the sixth floor window. Three men on the floor below also identified the source as a rifle on the floor above them.

So unless you have evidence of a second rifle on the sixth floor other than the one found there, she heard Oswald’s MC.

    Towner said, "...the LOUDEST crack of a rifle I had ever heard". That does Not match up with the sound of a Carcano being fired. Even an M-80 firecracker, (which many of us have used), is far louder than a carcano rifle or a run-of-the-mill firecracker. I believe that when Towner says, "...LOUDEST crack of a rifle I had ever heard", DQ's her describing a carcano or a standard fire cracker.
