I did but apparently you chose to ignore it.
No, you didn't.
You've mentioned assassination teams firing from the 5th floor (obviously you provide no evidence for this tinfoil claim).
You seem to believe that everyone involved in the discovery of the rifle was part of a "recreation" but that they originally "recreated" a Mauser then decided to "recreate" a Carcano.
Were they all in it together or were there two "teams" recreating different rifle discoveries?
It's very difficult to know what scenario you are actually putting forward as it seems to change as each point you make is shot down in flames.
Just sayin'
