Thx for your help on this, Steve. Now a deductive question comes to being, and I may have already answered it below:
Interesting on this above statement. Now, it starting to come to light on how this occurs with elements rotating within the barrel.
Here's the scenario: These Schneiders are mounted in PR-1050 turrets - MANUAL turrets - turrets that USED to be motorized, but the mechanics were taken off because they were a "complicated unit" - to follow the KISS (keep it simple, stupid) rule of the theatre.
Thus, with "stupid" people up in the booth, they were SLAMMING the turrets around to where they actually would knock the lateral alignment way out of kilter (in which I have threaten them with their very lives and positions if I EVER see anyone swing a turret disc around that hard again...!!!), whereas the motorized turret disc rotates in a far slower manner and being easy on the lens themselves.
Thus, with this rapid rotation, this action would "rotate" the elements inside the attachment barrel themselves, thus knocking out the prime focus within the barrel.
How close am I on this deduction that I just came up with?
