I have a Canon Serenar lens 50mm f1.9 collapsing type (not rigid) that needs the iris reset. How do you take one of these apart? I see a screw on each side of the aperture ring, a micro screw on the rim and the ring on the rear glass has notches so it can be unscrewed. I do not see anything else.

I really would like to put this back working right and use it.
