Working on tearing down an old Angenieux for a little project. I seem to be stuck on one of the external rings. See photos where I am pointing my screwdriver to focus marking ring. All external set screws have been removed. The most outer ring with the focal marks on it is totally loose and free spinning but still being retained by something I cannot see. Any thoughts on getting this removed? I have considered it is possibly just stuck but i have taken a torch to it and applied more than ample pressure with no luck. What am i missing here?!?
